Terms of service

Effective and last updated November 15, 2026. Quietlathe LLC, a Wisconsin limited liability company ("we", "us"), runs SheetLatch.

1. Acceptance

By using this site or SheetLatch, you agree to these terms and to our privacy policy. If you do not agree, do not use it. You must be at least 18, or the age of majority where you live, to buy a plan.

2. The service and early access

SheetLatch turns a Google Sheets tab into a cached JSON API and an MCP endpoint for AI agents. It is in early access: the website is live, but the API, free tool, accounts and checkout are not open yet. Joining the early-access list does not create an account, a purchase or a promise of a launch date. Features, limits and prices may change before launch. SheetLatch is not affiliated with or endorsed by Google.

3. Accounts and keys

When accounts open, you sign in with a one-time email link. You are responsible for your account and keys. A key opens only the sheet it was made for. Keep keys secret; tell us at ops@quietlathe.com if one leaks. You need a Google account and the right to share the sheet. Private mode works only on sheets you share with our service account, and you can remove that share at any time.

4. Acceptable use

  • Do not use the service for data you have no right to share, including other people's personal data without a lawful basis.
  • Do not use it as a general proxy or scraper, or to get around Google's limits.
  • Do not attack, overload or probe the service, or use keys you do not own.
  • Do not use it for anything unlawful.

We may throttle, suspend or revoke keys that break these rules or put the service at risk.

5. Plans, payments and taxes

Plans are Free, Maker ($5 a month), Pro ($15 a month) and Lifetime ($49 once, first 100 buyers). Prices are in US dollars, plus any taxes that apply. When checkout opens, payments will be processed by Stripe; we never see or store full card numbers. Monthly plans renew until you cancel, and you keep access to the end of the period you paid for. Limits are shown on the pricing section of the home page. At the limit, requests return an error until the next month; we do not bill for overages.

6. Lifetime plan

“Lifetime” means the lifetime of the SheetLatch service, not the buyer's. If we shut SheetLatch down, we will give at least 60 days' notice by email. If the shutdown happens within 24 months of your purchase, we will refund the Lifetime price pro rata for the months left in those 24 months. After 24 months from purchase, no shutdown refund is owed. Lifetime gives the Maker limits and features, with the first 100 buyers only. Lifetime purchases can also be refunded within 14 days, as set out in the refund policy.

7. Refunds

See the refund policy. It is part of these terms.

8. Intellectual property

You keep all rights to your sheets and data. You give us permission to read, cache and, when you call a write endpoint, write that data only to provide the service to you. We keep all rights to SheetLatch, its code, site and branding. Google Sheets is a trademark of Google LLC.

9. Third-party services

SheetLatch depends on Google, Cloudflare and, when checkout opens, Stripe and Resend. We do not control them. If Google is down or changes its limits, the service may be slow, serve cached data or fail.

10. Not a database, and no professional advice

Sheets have no transactions or locking. Do not rely on the service for payments, medical or safety data, or anything where a lost or stale row could cause harm. Nothing on this site is legal, financial, tax or other professional advice.

11. Disclaimers

The service is provided "as is" and "as available", without warranties of any kind, to the extent the law allows. We do not promise that it will be uninterrupted, error-free or fit for a particular purpose.

12. Limitation of liability

To the extent the law allows, we are not liable for indirect, incidental, special or consequential damages, or for lost profits or data. Our total liability for any claim is limited to what you paid us in the 12 months before the claim, or $50 if you paid nothing. Some places do not allow these limits, so they may not apply to you in full.

13. Indemnity

You will cover our reasonable losses from third-party claims caused by your data or your breach of these terms, including claims that you had no right to share the data in your sheet.

14. Termination

You can stop using SheetLatch at any time and revoke your keys. We may suspend or end your access if you break these terms or to protect the service. We may also shut the service down, and for Lifetime purchases section 6 applies.

15. Governing law and venue

Wisconsin law governs these terms, without regard to conflict-of-law rules. Any dispute will be heard in the state or federal courts in or for Outagamie County, Wisconsin, and you and we consent to those courts. There is no mandatory arbitration.

16. Changes

We may update these terms. The date at the top changes when we do. If you keep using the service after a change, you accept it. We will tell account holders by email about material changes.
