What Deficitto knows about you

Plain words first. If anything here is unclear, write to privacy@deficitto.app.

  1. What it reads from Apple Health

    Active energy, resting energy and weight, and only what you allow in the iOS permission sheet. Deficitto never writes to Apple Health. You can change access at any time in the Health app.

  2. What you give it

    Meal photos and notes, your goal weight and targets, and a small profile: sex, birth year and height. The profile is only used to estimate resting burn on days your wearable doesn’t report it.

  3. How meal photos are used

    Photos and notes are sent to our server to estimate calories and protein. When you’re offline they wait on your phone until you reconnect.

  4. Signing in

    Deficitto uses Sign in with Apple. If you choose to hide your email, we only see the relay address Apple gives us.

  5. Your invite request

    If you request an invite on this website, we keep the email you enter and, if you pick one, which wearable you use. We send one welcome email right away, then only write again with your invite. We use them for nothing else, and if you ask, we’ll delete them.

  6. What we don’t do

    No ads, and we don’t sell or share your data with advertisers.

  7. Deleting your data

    Write to privacy@deficitto.app from the email on your account and we’ll delete your account, meals, photos and weigh-ins.
