Privacy policy
Last updated 18 October 2026. Cut Buddy is run by company name to come. If you live in Washington, Nevada or another state with a consumer health data law, our consumer health data policy also applies to you.
The short version
- We collect what you tell the app so it can plan and track your food. We never sell it, never use it for advertising, and never let anyone track you across other apps.
- Your health answers are yes/no questions. We never store the names of your medications.
- Your conversations with Buddy are kept for 90 days, then deleted automatically.
- The AI that writes Buddy's replies never receives your name, email, phone number or the names of your medications.
- You can export everything or delete your account from Settings at any time.
What we collect
- Your account: your email address, or your Apple sign-in, and your name.
- Your profile: age or date of birth, sex, height, weight, body fat if you enter it, your goal and target weight, competition dates, diet, allergies, foods you avoid, cooking situation, budget and time zone.
- Health answers: yes/no answers to questions such as whether you are pregnant, take blood-sugar medication or have a history of an eating disorder. They decide what advice the app will and won't give you. We ask for your permission before asking them.
- What you log: meals and foods, water, weigh-ins, your training schedule and events.
- Conversations with Buddy, and the short notes Buddy keeps about you (for example, "trains at 6 am"). A note about your health is shown to you to keep or delete before Buddy uses it.
- Team information, if you join a team: your membership, what you agreed to share with your coach, and notes your coach writes about you.
- A parent's or guardian's contact details, if you are under 18 and join a team, so we can ask them to approve.
- Usage counts: how many messages you sent and what they cost us to answer. Never what you wrote.
Your camera, photos and voice are used on your phone only. Pictures of barcodes and labels, and anything you dictate, are not sent to us.
How we use it
To calculate your targets, plan your meals, answer your questions, show your progress, keep you safe (for example, never planning a weight-loss pace that is unsafe for you), and to understand how much the service costs to run. Nothing else.
Who we share it with
- Service providers that run the app for us, under contracts that limit them to doing so: Supabase (hosting), Anthropic (the AI behind Buddy, which receives your messages and the app's context with your name, contact details and medication names removed, and doesn't train on them), and Apple (sign-in and purchases).
- Your coach, only if you join a team, only what you turn on (your weight trend as a 7-day average, how closely you follow your plan, and warnings), and, if you are under 18, only after your parent or guardian approves. Your coach never sees your health answers, your conversations or a daily weight. You can turn sharing off or leave the team at any time, and it takes effect immediately.
- If the law requires it, or to protect someone's safety.
We do not sell your data or share it for advertising.
Feedback, and helping improve Buddy
Feedback. When you rate one of Buddy's replies or correct it, we keep the rating with that message and delete it when the message is deleted (after 90 days, or sooner if you delete the conversation). Corrections you choose to keep (for example, a food you don't eat) become notes in "What Buddy knows about me" or changes to your profile, which you can edit or delete.
Help improve Buddy (optional, adults only, off by default). If you turn this on, conversations you rate may be reviewed by named members of our team to improve Buddy's answers, the foods it recognises and the sources it uses. We remove your name, contact details and medication names, store these conversations without your account id, and leave out any conversation about your health. They are de-identified, and a separate code lets us delete them if you turn the setting off or delete your account. We keep them for up to 12 months. We don't use them to train AI models; if we ever want to, we'll ask you separately. People under 18, and accounts set up without numbers, can't turn this on.
How long we keep it
- Conversations with Buddy: 90 days.
- Ratings on Buddy's replies: with the message, so 90 days at most.
- Conversations you shared to help improve Buddy: up to 12 months, or until you turn the setting off.
- Everything else: until you delete it or delete your account.
- When you delete your account, everything is deleted from our database straight away, and we check that nothing is left. Encrypted backup copies are deleted within 30 days.
Your choices and rights
- See and export everything we hold: Settings → Export my data.
- Correct your profile at any time in Settings.
- Delete a conversation, a note, or everything Buddy remembers (Settings → What Buddy knows about me), or your whole account (Settings → Delete my account and data).
- Withdraw consent to team sharing at any time in Settings → Team, and to helping improve Buddy in Settings → Buddy.
- Or write to privacy email to come. We answer within 45 days.
Children and teenagers
Cut Buddy is not for children under 13, and the app won't let anyone under 13 sign up. For users aged 13 to 17, a parent or guardian must approve before any information is shared with a coach, and we send that request to them directly. Teenagers' data is never used for advertising and never sold. There is a version of this policy for parents and guardians.
Security
Data is encrypted in transit and at rest. Each person can reach only their own data, enforced by the database itself. On your phone, your sign-in is kept in the iPhone's Keychain and the app is hidden in the app switcher. If a breach affects your information, we will tell you, and the authorities where required, as the law requires.
Changes
If we change this policy in a way that matters, we will tell you in the app before it takes effect.
