Privacy

Short version: we collect the least we can get away with, we don't sell any of it, there are no ads and no trackers, and you can delete everything yourself at any time.

Last updated 7 September 2026

What we store

Only what you type in, plus what the app needs to work:

• Your email address — to sign you in and reset your password. It is never shown to another member. Ever.
• Your handle, and a display name and picture if you add them.
• Your sober date, if you enter one, and whatever you choose to fill in — a line about yourself, your town, your programs, what you're into, whether you're sponsoring.
• What you post — your words, and any photo or video you attach.
• Your messages to other members.
• Housekeeping — who you've blocked, what you've reported, which posts you liked, when you last read a thread.

What we never collect

• Your location. The app never asks for it, and if a photo or video you upload has GPS coordinates buried inside it, our server strips them out before the file is stored anywhere. The original is destroyed.
• Your contacts, your calendar, your other apps.
• Anything from advertisers or analytics companies.There are no third-party trackers in this app. Not one.

Who can see what

Posts and profiles are visible to other signed-in members. Nothing here is public on the open internet, and search engines are asked not to index it.

Anonymous posts are anonymous to everyone, including us in practice. The name on an anonymous post is a one-way code. Even a moderator reviewing a reported anonymous post is not shown who wrote it — the tool they use has no column for it.

Your day count can be hidden. Your town is hidden by default. If you set yourself as looking for a sponsor, only members with a year or more can see that.

Sage

Sage is a computer program that can answer questions about how this app works. It is not a person, it is not a member, and it will never appear here wearing a name and a face as though it were one. Wherever you see it, it says what it is.

What it is shown:

• A question you type into the help page.

What it is never shown, and cannot be:

• Your messages to other members. Not one, not ever.
• The reason you write when you pledge. That text is not shown to another member, to a friend, or to us — there is no way to ask the database for it, and Sage is not getting one.
• Your email, your handle, your sober date, or anything you have hidden on your profile. We send your question and nothing else, so the company that runs it could not identify who asked even if they wanted to.

That company is Anthropic. Their commercial terms say plainly that they may not train models on what we send them, and we read that ourselves rather than taking anybody's word for it. Nothing you ask Sage is stored on our side either — there is no transcript of it anywhere, the same way there is no record of you doing the breathing exercise.

Sage does not handle an emergency. If something you write reads like you are in danger, it does not try to talk you through it — you get the 988 line and a way to real people. It is not a counsellor, a doctor or a sponsor, and it is not a substitute for one.

We do not sell your information

Not to advertisers, not to insurers, not to treatment providers, not to anyone. There is no arrangement under which your data leaves this app in exchange for money, and there never will be — it would destroy the only reason this place works.

Leaving

Go to You → the pencil → Account → Delete your account. It removes your account, your posts, your replies, your messages, your photos and videos, and nobody can sign in as you again.

You'll be asked one question first: whether to also delete anything you posted anonymously. Those have no name on them and other people may have replied underneath, so it's your call, not ours.

Who we share with

We use three companies to run the app, and no others:

• Supabase — stores the database and files.
• Vercel — serves the app itself.
• Anthropic — answers the questions you ask Sage, and only those. See above for what it is and is not shown.

All three act only on our instructions. None of them is given permission to use anything for their own purposes.

Young people

Sober Book is for people 18 and over.

Asking us something

Write to hello@soberbook.app. A real person reads it.

If this policy ever changes in a way that matters, the app will say so rather than quietly updating this page.

What we ask of each other in here is a separate page: the rules. Deleting your account is here.
