Your health data stays yours

In short: we collect only what the app needs to time your fasts, count your steps and plot your weight. It is stored privately, never sold, never shown to advertisers, and you can download it or delete your whole account from the profile page.

Last updated 14 October 2026

What we collect

Account: your email address, how you sign in (email or Google), and an encrypted password.
Profile: name, avatar, age, height, gender, activity level and target weight — used for BMI and goal progress.
Health records: fasting sessions (start, end, duration), weight entries, daily step counts, and daily checklist ticks.
Preferences: weight units, step goal, reminders, notification and sound settings, and your chosen theme.
Messages you send us: contact messages, story submissions, and advertising requests (name, email, message).

Where it lives

Your records are kept in a private database tied to your account. The database itself refuses to hand one person's rows to another person.
Your device also keeps a local copy (browser storage) so the app opens fast and works offline; it syncs back when you reconnect.
Our hosting and email providers process data only to run the service for us. They are not allowed to sell it or advertise with it.

How it is protected

Everything travels over an encrypted connection (HTTPS).
Passwords are stored as cryptographic hashes, never as readable text.
Access needs a signed-in session; a signed-out visitor sees only public pages.
Only you and our small team can see your records — the team reads submissions only to review stories, contact messages and ad requests.

What we never do

We never sell or rent your personal or health data.
We never share it with advertisers or data brokers.
There are no advertising trackers or third-party analytics scripts on this site.
We never post your weight, steps or fasting data publicly — stories appear only after you submit one and an admin approves it.

Emails we send

Only what you asked for: account verification, password reset, and a welcome note when you register.
A short receipt when you send us a contact message, story or advertising request.
All system email comes from hello@dietsihat.com. We do not send marketing blasts.

Your controls

Correct anything at any time in your profile — weight, steps, fasting entries and profile details are all editable.
Turn notifications and sound effects off in Profile → Settings.
Change your password whenever you like in Profile → Settings.

Take your data with you

Profile → Settings → Export My Data downloads a single JSON file with your profile, preferences, fasting sessions, weight entries and step history.
The export is generated from your own account, so it contains only your records.

Delete your account

Profile → Settings → Delete Account removes your account and every fasting, weight, step and checklist record permanently.
Deletion is immediate and cannot be undone — export your data first if you want a copy.
We keep no hidden backup of your health records after deletion.

How long we keep things

Your records stay while your account is open, and are removed when you delete the account.
Contact messages, stories and advertising requests are kept until an admin removes them after handling the request.

Children and health advice

The app is not intended for children under 16, and we do not knowingly collect their data.
DietSihat is a tracking tool, not medical advice. Talk to a qualified professional before starting a long fast or a new diet.
