What WeighBetter does with your information
Last updated August 13, 2026
WeighBetter is run by one person, for a small group of people, as an early beta. This page says plainly what we collect and what happens to it. If anything here isn't clear, ask before you sign up.
What we collect
- Account details: your name, email address, and either a password (stored only as a cryptographic hash — we never see it) or a Google account identifier if you sign in with Google.
- Health information you give us: age, sex, height, weight and weigh-in history, goal weight, activity level, medications, diagnoses and conditions, and foods you won't eat.
- What you log: meals, calories and protein, meal photos, activity, and your conversations with the coach.
- Notes for your doctor that you choose to write, including any symptoms you record.
We do not use analytics or advertising trackers. The only cookie is the one that keeps you logged in.
Why we collect it
Solely to provide coaching to you: to calculate your targets, build your plans and grocery lists, respond in chat, track your progress, and produce your doctor-visit summary. That's the entire purpose.
Who it's shared with
- Anthropic. Your coaching conversations, your profile information (including medications and conditions), and your meal photos are sent to Anthropic's Claude API to generate responses, plans, and estimates. This is essential to how the service works. Anthropic processes this data as a service provider and does not use it to train their models.
- Resend handles our email delivery, so it processes your email address and the contents of account emails.
- Household members you invite. If you join a household, other members see your name, photo, weights, progress, streaks and badges. They do not see your medications, diagnoses, food logs, doctor notes, or coach conversations.
We do not sell your information, and we do not share it for advertising.
Where it lives
On a private server we operate, in a database that isn't reachable from the internet, over an encrypted connection. Backups are encrypted and kept for 14 days. Only the site administrator has access.
Your choices
- Delete everything. Settings → Delete my account removes your profile, logs, photos, plans, conversations, and doctor notes. It's immediate and permanent.
- See or correct your information any time from Settings and the intake form.
- Leave a household to stop sharing progress with its members.
- Ask us anything about your data by emailing the address below.
What this service is not
WeighBetter is not a healthcare provider and is not a substitute for one. We do not diagnose, treat, or prescribe. Your medical decisions belong with you and your doctor.
Children
WeighBetter is for adults. Don't create an account if you're under 18.
Changes and contact
If this policy changes in a way that matters, we'll email you. Questions, corrections, or deletion requests: rayhonsandrew@gmail.com.
