Privacy Policy
Become keeps your habit data private to your account, uses it only to run the app and its AI coach, and never sells it or shows ads.
Become is a habit-tracking app run by Darren Kirkham ("we", "us"). This policy explains what information the Become app and its services collect, how it is used, who helps us process it, and the choices you have. It applies to the Become iPhone app, including test versions distributed through TestFlight.
Information we collect
We collect only what you enter into Become and what the app needs to work.
| Information | Examples | Why |
|---|---|---|
| Account details | Your email address and password | To create your account and sign you in. Your password is stored only in hashed (scrambled) form; no one, including us, can read it. |
| Habits | Habit names, icons, categories, goals and reminder times | To show and track your habits. |
| Check-ins | The dates you checked in on each habit | To calculate your progress, streaks and history. |
| Settings | Week start day, appearance, whether the AI coach is on, whether you've seen the intro | So your settings follow you to every device you sign in on. |
| Time zone | For example, America/Denver | So reminders and coach messages arrive at the right local time. |
| Coach messages | Nudges, weekly reflections and monthly reports written for you | To show them in the app and keep your history of reflections. |
| Device push token | An identifier for your phone from Apple's notification service | To send you coach notifications, if you allow notifications. |
We do not collect your location, contacts, photos, microphone, advertising identifier, or browsing activity. Become has no third-party analytics or advertising SDKs.
How we use your information
We use your information only to provide Become to you:
- Run your account and keep your habits in sync across your devices.
- Show your progress, streaks and history.
- Schedule the habit reminders you set up, on your phone.
- Write personalized coaching (nudges, weekly reflections and monthly reports) when the AI coach is on.
- Send account emails you ask for, such as password reset codes and email-change codes.
- Keep the service secure and fix problems.
We do not sell your information, share it for advertising, or use it to build profiles for anyone else.
Service providers we use
A few companies process information on our behalf to run Become. Each receives only what it needs for its job.
| Provider | What it does for Become | What it receives |
|---|---|---|
| Supabase | Hosts accounts, the database and the AI coach's server code (United States) | Everything listed above |
| Anthropic | Its Claude AI model writes your coaching messages | A summary of your habit statistics (see AI coaching below); never your email or password |
| Resend | Delivers password-reset and email-change emails | Your email address and the one-time code |
| Expo | Relays coach notifications to Apple | Your device push token and the notification's title and text |
| Apple | Delivers notifications to your iPhone, and distributes the app through TestFlight and the App Store | Your device push token and notification content; TestFlight shares its own usage and crash data with us under Apple's policy |
We may also disclose information if required by law, or to protect the safety of our users or the service.
AI coaching
Become's coach is written by Claude, an AI model made by Anthropic. When the coach runs, our server works out statistics from your check-ins and sends Claude a short summary containing:
- Each habit's name, category and goal.
- How much of each goal you completed in the period, how that compares with the period before, which weekdays you tend to check in, and your streak length.
- Today's date, your week start day, and titles of your last few coach messages (so it doesn't repeat itself).
The summary never includes your email address, password, or account ID. Under Anthropic's commercial terms, data sent through its API is not used to train its models by default. The AI's suggestions are general encouragement, not medical, mental-health or professional advice.
You can turn the coach off at any time in Settings → AI Coach. While it is off, no summaries are sent and no new coach messages are written.
Security
Information travels between the app and our servers over encrypted connections (HTTPS) and is encrypted when stored. Database rules restrict every account to its own data, so one user can never read or change another user's habits, check-ins, settings or coach messages. A copy of your data is also kept on your phone so the app works offline; signing out removes it from that phone.
No system is perfectly secure. If we learn of a breach that affects your information, we will notify you as the law requires.
Keeping and deleting your information
We keep your information for as long as you have an account.
You can delete your account at any time in Settings → Account → Delete account. This permanently deletes your account, habits, check-ins, settings, coach messages and push tokens from our database straight away. Copies may remain for a short time in routine backups and in our providers' logs before they are overwritten.
Your choices and rights
- See and change your data: everything you've entered is visible and editable in the app.
- Turn off the AI coach: Settings → AI Coach.
- Turn off notifications: in your iPhone's Settings → Notifications → Become.
- Change your email: Settings → Account → Change email.
- Delete everything: Settings → Account → Delete account.
- Get a copy or ask a question: email us and we'll respond within 30 days.
Depending on where you live (for example, California or the European Union), you may have further rights to access, correct, delete or move your information, or to object to how it's used. Contact us to exercise them.
Children
Become is not directed to children under 13, and we do not knowingly collect information from them. If you believe a child under 13 has created an account, contact us and we will delete it.
Changes to this policy
If we change this policy, we will update the effective date above, and for significant changes we will tell you in the app or by email before they take effect.
