Support
Updated 12 October 2026
One address, read by a person: [email protected]. There is no ticket maze and no chatbot in front of it.
The Keep has not launched yet. If you are writing before launch it is probably about the waitlist, and we can help with that today. Everything else on this page describes how support works once the app is open.
What to expect
- We reply within one business day, and usually much faster.
- We will tell you what we actually know. If something is broken we will say it is broken rather than suggest you reinstall.
- We cannot see your records. The substance of your case lives on your device, so when you ask for help we may need you to describe what you are seeing. That is a consequence of the privacy architecture, not an evasion.
Common things
Getting into your account
There are no passwords. Enter your email and we send you a sign-in link that works once and expires in fifteen minutes. If it has not arrived in a couple of minutes, check the spam folder before asking for another, because requesting a second link invalidates the first.
Billing
Write to us and say what you want changed. Subscriptions purchased through the App Store or Google Play are managed in those stores and have to be cancelled there — we cannot cancel them on your behalf, which is a store rule rather than ours.
Getting your records out
You can export everything at any time from inside the app. The export is designed to be readable without The Keep, so it stays useful if you stop using us.
Closing your account
See how deletion works. You can do it yourself inside the app, and we will do it for you if you would rather write.
Reporting a security problem
Write to [email protected] with “security” in the subject line. We will acknowledge within one business day. We will not threaten you for reporting something in good faith.
What support cannot do
We are not a law firm and cannot give you legal advice — not about your order, not about what you should do next, not about whether something is a violation. We can tell you how the product works. For what your order means for you, talk to an attorney licensed in your state.
