Terms of Service
Last updated 24 August 2026. Receipts is operated by Receiptsproof Pte. Ltd. (UEN 202638224N), a private limited company incorporated in Singapore.
The most important term, first. Receipts produces evidence, not a verdict. It does not certify that you wrote something and it cannot force anyone to believe you. It is not unforgeable, and we never claim it is. What it does is show how a document was written, in detail, so a human can judge for themselves.
What you get
- Free, forever: keystroke recording, replay, proof links, all signal checks visible to whoever you share with, and backup to your own Google Drive. The evidence is never paywalled.
- Defense Pack, $19 once: the in-app history list is kept indefinitely rather than showing the last 40 days, for as long as Receipts operates, plus the printable exhibit, the letter for your teacher, and the Google Docs cross-check. One payment. It does not renew. To be clear: every record you have saved to your own Drive or shared as a proof link stays fully usable for free, forever; paying is for convenience and polish, never for the evidence itself.
- Premium, $4 per month: the same paid features on a monthly basis. Cancel at any time.
A paid plan protects writing you do from that point on. If you have never written in Receipts, buying a plan today does not create a record for an essay you wrote last week. The one exception is the Google Docs cross-check, which can read revision history Google already holds.
What this is not
- It is not a guarantee of any academic outcome, and not a promise that nobody will ever question your work. Your school decides what it accepts as evidence.
- It is not an AI detector and produces no score claiming a text is or is not AI-written.
- It cannot prove a negative. It cannot show that you did not read text elsewhere and retype it, and no tool can.
- Absence of a signal is not evidence against anyone. Phone keyboards, dictation and assistive input legitimately produce fewer signals.
Your responsibilities
- Use Receipts for your own work. Do not present someone else's record as yours.
- Do not attempt to fabricate, tamper with or automate a record.
- Keep your proof links to people you intend to show your work to. Anyone holding a link can replay that document.
- Follow your school's rules. Receipts does not override them.
Your writing is yours
You own everything you write. We claim no licence over it, and could not use it in any case, because it is never sent to us. Files created in your Google Drive belong to you.
Payments and refunds
Purchases are processed by Polar, acting as merchant of record. Your receipt and your licence key are emailed by Polar. Refunds and billing questions are handled through Polar, and you can start either by replying to that receipt. If you bought something and it does not work, ask for a refund because of that and you will get one.
Your licence key is tied to the email address you paid with. Keep the email.
This refund policy covers individual Premium and Defense Pack purchases only. School and organisation licences are never refunded except in the specific cases named in the school licence terms.
Availability
Receipts is operated by Receiptsproof Pte. Ltd. and built and run day to day by one person. It is provided as-is, without any guarantee of uptime. Because your writing lives in your browser and your own Drive, the service being unavailable does not put your work or your records at risk.
Age
Receipts is intended for students, including school-age students. If you are under 18, a parent or guardian should make any purchase.
These terms cover individual purchases only. If you are buying on behalf of a school, district, tutoring organisation or other educational enterprise, that purchase is made by the organisation, not by any individual student, and is governed by the school licence terms instead, signed by an authorised adult on the organisation's order form.
Liability
To the extent permitted by law, liability is limited to the amount you paid, which for most people is nothing. Receipts is a tool for presenting evidence, and the consequences of any academic decision rest with your institution.
Governing law
These terms are governed by the law of Singapore. Purchases are handled by Polar as merchant of record, and refund and billing disputes go through Polar first.
Contact
Anything in these terms can be raised with Receiptsproof Pte. Ltd. at hello@receiptsproof.com.
Changes
These terms may change. The date at the top will change with them, and material changes will be noted on the site.
24 August 2026: added a line under Age clarifying that purchases by a school, district, tutoring organisation or other educational enterprise are made by the organisation, not by an individual student, and are governed by the school licence terms instead.
