Tend is a small, free, open-source app run by Nathan Watkins (n8builds.dev). This page says plainly what it keeps and why.
What Tend stores
- Your account: your email address, and your GitHub name and picture if you sign in with GitHub.
- The people you add: a name, and only if you choose to add them, a phone number and private notes. Phone numbers and notes are encrypted before they are saved.
- Their consent state, the topics you picked, their timing rules, the messages you scheduled, sent or skipped, and changes to their consent.
- Your settings: time zone, preferred Bible translation and whether you want email reminders.
- Short-lived counters (hashed, not readable) that limit how many sign-in emails can be sent, to stop abuse.
What Tend does not do
- It never connects to Signal, never reads your Signal contacts or messages, and never sends anything for you.
- It does not use analytics, advertising or tracking, and it does not sell or share your data.
- It does not send anyone’s details to an AI service.
The people you add
They never signed up to Tend, so please add only what you need: a name is enough. Each person gets a private stop link you can include in messages; if they use it, Tend stops reminding you to message them, and the page they see never shows your email or their details.
Where it lives
Tend runs on Cloudflare Workers. Data is stored in a Turso (libSQL) database in the United States. Sign-in and reminder emails are sent through Cloudflare Email Service. Cloudflare Turnstile may check the sign-in form for bots.
Your control
- Export everything as a file from Settings.
- Delete any person, and all of their history, from their page.
- Delete your account from Settings: everything is removed immediately.
Security
Encryption keys are held only by the server, so encryption protects against a leaked database copy, not against a compromise of the server itself. Report a security problem as described in the project’s security policy.
