Terms & Privacy

Terms of sale. Start with the summary at the top, then sections 1–25.

1. Seller

“Klip”, “we”, or “seller” means the seller named above. “You” means the buyer.

2. Definitions

Seller means Truong Minh Huy at the address above. Buyer / you means the person placing the order. Apps means the desktop applications Klip and KlipOCR. License code / key means the string that unlocks paid features. Seat means one activated device for one code. Merchant of Record means Lemon Squeezy (Link, LLC f/k/a Lemon Squeezy LLC), the party that sells to you and handles payment, tax collection, and chargebacks. Checkout means the Merchant of Record-hosted purchase flow. Free tier means the no-key functionality described in section 5. Validation means the periodic license check in section 11; offline allowance means the 30-day offline period a successful check grants.

3. Precedence

If documents conflict, this order applies, top first: (a) mandatory law that cannot be waived; (b) the Lemon Squeezy Buyer Terms for matters Lemon Squeezy handles as Merchant of Record (payment processing, tax collection at checkout, chargebacks, and any refund Lemon Squeezy itself grants); (c) these Terms including the EULA in section 10; (d) the Privacy Policy on this page; (e) product and seat details stated on the License page at purchase. Our no-refund rule and best-effort support do not bind Lemon Squeezy, your bank, or the law.

4. Eligibility

You must have legal capacity to enter a contract where you live, and be old enough to buy under local law. The apps require a compatible computer; activation requires a one-time internet connection and a working email address you control. Paid features also require periodic validation while online (section 11). No account is required. We do not sell to resellers; each order is for your own use.

5. Products and prices

Summary: fixed one-time prices below — no refunds, and support is best-effort, because each sale is one final code for one device.

Except where Article 25 of Law 19/2023 prohibits, to the maximum extent permitted; any void part is severed and the rest stands.

We sell perpetual licenses for two desktop apps: Klip and KlipOCR.

• Klip — $4.99 USD: LaTeX, Markdown and HTML to office.
• KlipOCR — $2.99 USD: screenshots and scans to text.
• Bundle — $6.99 USD: one Klip code plus one KlipOCR code in a single checkout.

Prices are shown and charged in USD. The price shown at checkout is the price you pay, plus any tax stated at checkout (see section 6). Buy only via the Merchant of Record; codes elsewhere are not genuine. Free tiers ($0) keep working without a key on a rolling 7-day basis: Klip pastes up to 1000 characters, 21 free in the first 7 days, then 14 per rolling 7 days; document conversion (document mode) is paid. KlipOCR 21 free snips in the first 7 days, then 14 per rolling 7 days, no length limit on input per snip; converted output text is capped at 500 KB with a truncation marker; document mode is paid. The apps contain no telemetry or analytics. The price buys the as-is version only — updates are never promised, although updates that are made available may continue after revocation (section 11.5). No delivery-time promise is made beyond the automated email send in section 9 (typically within 24 hours); delay queries go to Lemon Squeezy. Enterprise or team packs are currently Coming later and, if offered, state their own seat count on the License page at purchase; each seat remains one device, non-transferable.

6. Taxes at checkout

Summary: any tax is added at checkout by the Merchant of Record — never by us directly.

Except where Article 25 of Law 19/2023 prohibits, to the maximum extent permitted; any void part is severed and the rest stands.

Depending on your country, VAT, GST, sales tax, or other indirect taxes may apply. Any such taxes are calculated and collected at checkout by our Merchant of Record and shown before you pay. The receipt or invoice issued at checkout states the final total, including any tax charged. For Vietnam (Decree 52 on e-commerce; MoIT notice): we will complete any required notification to the Ministry of Industry and Trade before accepting paid orders from Vietnam. A Merchant-of-Record receipt is not a Vietnamese red (VAT) invoice; the seller declares personal income tax on receipts as required.

7. Ordering flow

Summary: pay plus key sent equals a completed order — activation changes nothing and extends no withdrawal right.

Except where Article 25 of Law 19/2023 prohibits, to the maximum extent permitted; any void part is severed and the rest stands.

1. Choose a product on the License page (Klip for $4.99 USD, KlipOCR for $2.99 USD, or the bundle for $6.99 USD).
2. Check out through the Merchant of Record (Lemon Squeezy).
3. Type a correct, working email address; that address receives the key.
4. Pay the USD total shown, including any tax stated at checkout.
5. Receive the key by email and activate it yourself in the application.

Your order is complete when payment succeeds and the key is sent (see section 9); activation is irrelevant to completion and does not extend any withdrawal right. Double-check the edition and your email before paying — all sales are final (see section 12). E-transactions: your click to pay forms the contract; order records are archived for 3 years. You are given reasonable review time before paying, and you may request a storable and printable copy within 7 days (write under section 20; print or save this page).

8. Payment — one-time, no subscriptions

Summary: one charge per code, never recurring — checkout runs through the Merchant of Record.

Except where Article 25 of Law 19/2023 prohibits, to the maximum extent permitted; any void part is severed and the rest stands.

Every purchase is a one-time payment. There are no subscriptions, no recurring charges, and no auto-renewals. You pay once for each license code. Checkout is handled by our Merchant of Record; we never see or store your full card details.

9. Delivery by email

Summary: delivery ends when the code is sent — delays, spam filters, mistyped addresses, and lost codes do not reopen it.

Except where Article 25 of Law 19/2023 prohibits, to the maximum extent permitted; any void part is severed and the rest stands.

License codes are sent once by email via Resend to the address you type at checkout. Delivery is complete when the code is sent; risk passes on send. Delays, spam/promotions filtering, inbox-full, a mistyped address, a lost or deleted code, and activation failure do not reopen delivery. No delivery-time promise is made beyond this automated send (typically within 24 hours); delay queries go to Lemon Squeezy. Our policy is not to reissue codes.

Your duties: type a correct, working email; check spam on your own; back up your code — it is shown once and we will not reissue, resend, reset, transfer, or troubleshoot it. Lost key, new device (including repair / hardware change), wiped disk without a key backup, non-receipt, or activation failure = buy a new license if you want one. The free tiers keep working without a key.

Using Resend to send keys, and Lemon Squeezy as Merchant of Record to take payment, does not exclude our liability as seller for supply of the digital content where mandatory law holds the seller liable. Except where mandatory law holds the seller liable (see section 3), no reissue, resend, or refund is owed.

10. End-User License Agreement (EULA)

Summary: one code, one device, perpetual on that device — validated about daily online, fully offline for 30 days plus 14 days grace. No moves, no reissues, except what Lemon Squeezy or mandatory law decides.

This section is the End-User License Agreement. It is kept here as the single source — the apps and this site refer to this page rather than a separate copy.

10.1 Grant. On full payment and subject to your compliance with these Terms, we grant you a personal, non-exclusive, non-transferable license to install and use one purchased copy per code, as follows: a Klip code unlocks Klip; a KlipOCR code unlocks KlipOCR; a bundle unlocks both, one code per app.

10.2 One device, no transfer. Each code covers one device only. The license is perpetual for that device and this version — yours to keep on that one device, this version only (updates are never promised; section 5) — subject to periodic validation in section 11 and termination under section 17, but it may not be shared, resold, lent, transferred to another person, or moved to another device. Reinstalling on the same device is allowed. Enterprise or team packs are currently Coming later and, if offered, state their own seat count on the License page at purchase; each seat remains one device, non-transferable.

10.3 What you may not do. You may not sell, rent, sublicense, publish, or redistribute the apps or your codes; circumvent activation, validation, or free-tier limits; reverse-engineer or extract source except where mandatory law permits; or use the apps in breach of law.

10.4 Ownership. The apps remain our property. This is a license, not a sale of the software itself. You retain ownership of your own inputs and documents. No rights are granted except as written here. You grant us a non-exclusive, worldwide, royalty-free licence to use any feedback you submit (to improve the apps); we have no obligation to use, credit, or compensate it, and you keep ownership of the feedback itself.

10.5 Offline use and validation. Both apps work offline between checks. Activation needs an internet connection once; while online, the app checks the license in the background about once a day. A successful check covers 30 days of full offline use, plus a 14-day grace period (44 days total from the last successful check). After grace, the app returns to the free tier and paid features resume after the next successful check. No account is required.

10.6 No reissue, no reset, no transfer — carved. Each code locks to one device at first activation and never moves. We will not reissue lost or deleted codes. We will not reset activations for new or repaired devices. We will not transfer seats between devices or persons, or troubleshoot activation — carved only for (a) whatever Lemon Squeezy in its discretion decides as Merchant of Record, and (b) rights under mandatory law that cannot be waived. Need the app on another device = new purchase. Enterprise/team packs, if offered, state their seat count on the License page; each seat is still one locked device under this 10.6.

10.7 Best-effort support under this EULA. The license price buys the code as-is. Support is best-effort through the in-app Help & Feedback portal; no reply, response time, fix, or troubleshooting outcome is guaranteed — see section 13. You complete activation yourself; the app validates online when a connection is available and works offline between checks (section 11). If activation fails on your machine, section 10.6 applies.

11. License validation and revocation

Summary: the license is perpetual for one device, but paid features need a check about daily online. Offline, they keep working for 30 days plus a 14-day grace period (44 days), then the app returns to the free tier until the next successful check. Revocation only follows a refund, a chargeback, or proven abuse, and you can appeal.

11.1 Perpetual license, periodic validation. A license is perpetual for the one device it is activated on and this version (updates are never promised; section 5) and does not expire on a calendar date. Paid features require periodic validation: the app checks the license in the background about once a day while an internet connection is available (every 24 hours, give or take 6 hours; every 6 hours, give or take 30 minutes while in grace — first attempt 10–30 seconds after launch). A successful check issues a new 30-day offline allowance. Validation never blocks or interrupts a conversion; checks run automatically in the background without interrupting your work. No account is required.

11.2 Offline window and grace. Paid features work fully offline for 30 days after the last successful check. If the app cannot reach the license service, a further 14-day grace period applies (44 days total from the last successful check). The app's license status shows a countdown of days left in grace, and a warning appears during grace. After grace, the app continues in the free tier and paid features resume after the next successful check. Being offline alone never revokes a license.

11.3 What validation sends. A validation request contains only the license ID, seat number, device proof (the hashed hardware identifier, device public key, secure request verification), IP address, and a timestamp. It does not contain document content, clipboard content, file names, or your usage history. The apps contain no telemetry, analytics, or advertising SDKs. See Privacy section 4.

11.4 Revocation grounds. We revoke a license only for (a) an actual refund, (b) a chargeback, or (c) proven abuse — for example stolen payment details, published or resold codes, or bypassing activation or free-tier limits. An open dispute, a support request, or a failed validation does not revoke a license. A refund or chargeback decided by Lemon Squeezy or your bank revokes the affected order's license.

11.5 Effect of revocation. After a revocation takes effect, paid features stop immediately; a conversion already in progress is allowed to finish. The app keeps working in the free tier, and revocation does not block app updates: the app may continue to receive all updates that are made available (updates are never promised; section 5). A device that stays offline does not receive notice of the revocation and keeps paid features only until its current allowance and 14-day grace period end, then returns to the free tier. Revocation does not delete your documents or data on your device.

11.6 Appeal and restoration. You may appeal a revocation by writing to louistruong1111@gmail.com with subject APPEAL, your license ID or order email, and a short explanation. Appeals are reviewed by a person, not automatically. We target a response within 7 days. If the revocation was made in error or is reversed, we restore the license and paid features. An appeal does not extend any refund right (section 12).

11.7 No remote wipe. Revocation changes license status only. It does not remotely erase, lock, or alter documents, clipboard content, or other files on your device.

12. Refunds — all sales final

Summary: every sale is final — pay plus key sent completes it; only Lemon Squeezy or mandatory law can override, because a delivered code cannot be returned.

All sales are final. Pay + sent = completed sale; activation is irrelevant and does not extend any withdrawal right. We grant no refunds — carved only for (a) whatever Lemon Squeezy itself decides as Merchant of Record, and (b) rights under mandatory law that cannot be waived — not otherwise for change of mind, duplicates, wrong editions, lost keys, new devices, non-delivery, or activation failure. Lost key, new device, deleted email, failed delivery or activation = buy a new license if you want one; the free tiers keep working without a key. We provide no refund help and promise no reply.

Contact Lemon Squeezy first for any payment, tax-invoice, chargeback, or refund question; we will not handle those. The legal seller at checkout is Lemon Squeezy as Merchant of Record (Link, LLC f/k/a Lemon Squeezy LLC). Per its Buyer Terms, Lemon Squeezy may in its sole discretion grant or refuse refunds on a case-by-case basis, and may refuse where it suspects fraud or abuse. Any Lemon Squeezy replacement is solely Lemon Squeezy’s act — it grants no second code and no help from us. Any time limit Lemon Squeezy states for particular request types (for example certain tax-code-related requests, or its 60-day sales-tax refund window) is set by Lemon Squeezy, not by us; we promise no general 60-day product-refund window. For technical non-delivery Lemon Squeezy may provide a replacement or a refund under its own terms. Our no-refund rule does not bind Lemon Squeezy, your bank, or the law.

Licenses are revoked only after Lemon Squeezy or the bank decides the dispute, or where abuse is proven (for example stolen payment details, chargeback abuse, published or resold codes, bypassing activation) — not on a mere open dispute. Granted credits revoke that order's keys with no replacement from us.

EU customers: keys are delivered immediately as digital content. Withdrawal ends when supply begins with your express consent plus acknowledgement of loss of right. Lemon Squeezy's checkout presents its Buyer Terms and requires you to accept them before payment; those Buyer Terms include that consent and acknowledgement, and Lemon Squeezy records your acceptance. A policy page alone does not create the waiver. Nothing here excludes rights under mandatory law that cannot be waived (VN warranty/defect remedies, EU/UK conformity, fraud/wilful misconduct).

13. Support and contact

Summary: in-app Help & Feedback is the support channel; replies are best-effort, and email may get no reply.

In-app support. The apps provide a 24/7 Help & Feedback portal. Reports are stored in Supabase and may receive an in-app reply. We aim to help, but replies, response times, and fixes are best-effort — no reply, resolution, or response time is guaranteed. Do not rely on support for anything time-critical.

Email is not a support channel. louistruong1111@gmail.com is monitored on a best-effort basis solely for privacy-rights requests, license-revocation appeals (subject APPEAL), mandatory consumer-law notices, and EU dispute-resolution correspondence. Messages asking for keys, resets, refunds, or fixes may receive no reply, and no reply creates no obligation. See the contact note below.

EU dispute-resolution: consumers in the EU may use the European Commission's dispute-resolution platform at EU consumer redress platform (the old dispute resolution site was retired on 2025-07-20). For dispute resolution correspondence by email, write to louistruong1111@gmail.com with subject COMPLAINT plus your order email and a short description; mandatory notices with subject COMPLAINT are acknowledged within 3 days — acknowledgement is not a fix and creates no support duty. Seller: Truong Minh Huy, 128 Le Quang Hoa, Vietnam.

Complaint handling (Article 31): (1) send to the section 20 address with subject COMPLAINT; (2) we handle it under mandatory law; (3) we respond only as the law requires. Support-seeking messages (keys, resets, refunds, fixes) are not COMPLAINT notices even if labeled so — a support request does not become a legal notice even if it uses the word Complaint in the subject line. Auto-acknowledgement confirms receipt only and promises no fix. Order and delivery records are retained as proof of sending and payment.

14. Warranty

The apps are provided “AS-IS”, without warranties of any kind — express, implied, or statutory, including merchantability, fitness for a particular purpose, and non-infringement — to the maximum extent permitted by law. Where you are a consumer in the EU or EEA, nothing here limits your mandatory statutory rights, including the conformity guarantees that cannot be excluded under applicable consumer law.

Vietnam (Article 30) annex: no general warranty is given; for a compulsory defect, the ladder is one replacement key if possible, otherwise a Merchant-of-Record refund under its terms; transport or delivery cost of a replacement is on the seller where the law requires; the emailed key and the stated period serve as the certificate. Verify OCR outputs before any professional reliance — KlipOCR is an aid, not a certified source. Accessibility: pages aim for plain readable text; report access barriers via the section 20 legal-notices address.

15. Liability limit

To the maximum extent permitted by law, our total liability for any claim arising from a purchase or use of the apps — whether in contract, tort, or statute — is limited to the price you paid for that license (Klip $4.99 USD, KlipOCR $2.99 USD, or bundle $6.99 USD, as applicable). We are not liable for indirect, incidental, or consequential loss, including examples such as lost documents, lost profit, reformatting costs, or time spent re-creating work. The preceding sentence does not extend to consumers where local law forbids it, and the price-cap limit does not survive where its essential purpose is said to fail for a consumer.

Nothing in these terms limits liability where the law does not allow it — including liability for fraud or wilful misconduct, and any consumer or product-liability rights that cannot be limited or excluded.

Recall and compensation: where mandatory law requires recall or compensation for defective digital content, we comply to that extent. Vulnerable consumers (elderly people; persons with disabilities; children; ethnic minorities and people living in ethnic-minority, mountainous, island, or disadvantaged areas; pregnant women and women nursing a child under 36 months; persons with fatal diseases; members of poor households): ask via the section 20 legal-notices address for clearer explanation. Activities not listed in the Decision 07/2024 product lists are not claimed as certified (Article 28 disclaimer).

16. Indemnity

To the extent permitted by law, you agree to cover our reasonable, foreseeable losses caused by your wilful breach of these terms or your unlawful use of the apps (for example sharing or reselling codes, or bypassing activation), capped at the price you paid for that license. We will notify you promptly of any third-party claim, give you control of the defence where you accept it in writing, and mitigate. This section does not apply to consumers where local law forbids it, does not cover losses caused by our own fault, and does not limit your mandatory consumer rights.

17. Termination

We may refuse, cancel, or revoke a license for refund, chargeback, or proven abuse — proven abuse means facts we can evidence, for example stolen payment details, published or resold codes, or bypassing activation or free-tier limits. Except for fraud or a decided refund/chargeback, we give written notice to your order email and 14 days to cure where curable before a revocation takes effect. An open dispute does not revoke a license (section 11.4). After a revocation takes effect, paid features stop immediately (a conversion already in progress may finish); the app keeps working in the free tier, and app updates may continue under section 11.5. Revocation does not remotely erase or lock documents or other files on your device. You may appeal under section 11.6. Nothing here grants a right to new installs, transfers, refunds, or support after termination.

18. Governing law and disputes

These terms are governed by the laws of Vietnam. If you buy as a consumer, the mandatory consumer protections of the country where you habitually live continue to apply on top of these terms where the law requires it.

Consumers in the EU may use the European Commission's dispute-resolution platform at EU consumer redress platform, or write to us under section 13 for dispute resolution correspondence. No court venue is named here and no arbitration is imposed — nothing stops you from bringing a claim where your local law gives you that right.

Ambiguities are construed in favour of the consumer (Article 24). For consumers in Vietnam the Vietnamese version controls except where English is more favorable; for buyers outside Vietnam the English version controls (Article 23(2)). The UN Convention on Contracts for the International Sale of Goods (the international sales convention) does not apply. Export and sanctions: subject to applicable export controls and sanctions; you self-certify you are not a denied or sanctioned party and will not export in breach of law; we transact with no sanctioned party.

19. Force majeure

Neither party is liable for delay or failure caused by events beyond reasonable control — for example natural disasters, war, network or infrastructure outages, or government orders — except for checkout payment obligations already due at the time of the event. Delivery-by-email duties in section 9 still apply once the event ends.

20. Notices

Send legal notices to louistruong1111@gmail.com. An email you send is deemed received when it reaches our mailbox; routine site notices posted on this page are deemed received when posted. Material changes, termination, or revocation notices to you are sent to your order email and in-app where possible, and take effect no earlier than 14 days after sending except for fraud or a decided refund/chargeback. Mandatory notices with subject COMPLAINT are acknowledged within 3 days — acknowledgement confirms receipt only and promises no fix (see section 13). Marketing or support requests sent to this address are not notices and may receive no reply. Government requests: we notify you unless prohibited by law.

21. Assignment

You may not transfer or assign your license or rights — each seat is locked to one device and one buyer (see section 10). We may assign these terms only with a transfer of the Klip business, only if your rights are not reduced, and only after 30 days' advance notice on this page and to your order email where possible; if the assignment materially degrades your rights you may terminate and drop to the free tier. Seller assignment never moves buyer seats — each seat stays locked to its device and buyer.

22. Severability

If any part of these terms is found invalid or unenforceable, that part is cut to the minimum needed — replaced where possible with a valid term closest to the original intent — and the rest continues in full force.

23. Entire agreement

These Terms (including the EULA), the Privacy Policy on this page, and the product details on the License page at purchase are the entire agreement for a license purchase. They replace earlier statements about price, delivery, refunds, or support. No oral variation: only the posted terms as purchased apply, and contrary oral claims are estopped. Survival: sections 10–17 survive termination. Insolvency: if either side becomes insolvent, a paid license keeps working offline between checks for the 30-day window plus 14-day grace, but no new installs, transfers, refunds, or support are owed either way. Government requests are handled under section 20. The apps are not health-privacy law-ready — do not use them for protected health information.

24. Changes to these terms

We may update these terms (for example when checkout, taxes, or contact details change), and each version carries its date above. The version in effect when you purchased applies to your order — later changes do not retroactively alter completed sales. The current version is always the one published on this page. This is the first published version. Future changes will be recorded in the history table below, and the version in effect at purchase will be archived and retained for 3 years.

25. Version history

Contact note: louistruong1111@gmail.com is legal-notices-only. Privacy-rights and mandatory consumer-law notices are answered within 30 days. Revocation appeals (subject APPEAL) target a reply within 7 days (section 11.6). Messages asking for keys, resets, refunds, or fixes may receive no reply. Related page: License page.
