Privacy & data

Our philosophy

You should understand your behavior — not surrender your data.

This is not a black box.
This is a mirror.

We don’t exist to control you, track you across the internet, or sell your data.
We exist to help you see what you’re already doing — more clearly.

What we collect

When you use Leptir, we store only what is necessary to make the product work:

  • Meals you log (text and optional images)
  • Workouts you log
  • Weight entries (if you choose to track them)
  • AI-generated estimates (macros, scores, assumptions)
  • Your Telegram username / ID (for communication)

That’s it.

We do not collect unrelated personal data.

How your data is used

To show you transparent readouts and patterns.

  • Interpretation estimates nutrition where you did not state it explicitly
  • We store your history so you can see continuity over time
  • We use your data only to operate Leptir for you — not for ads

We do not use your data for advertising.

AI & assumptions

  • Some values are estimates
  • Some assumptions are made (ingredients, portions)

You can always edit your logs.
You are never locked into an AI result.

You are the source of truth — not the AI.

Where your data lives

Your data is stored securely in a database (e.g., Supabase/PostgreSQL).

  • Secure infrastructure
  • Controlled access
  • Separation between environments

No system is perfect, but we handle your data responsibly.

What we don’t do

  • We do not sell your data
  • We do not share your data for marketing
  • We do not track you outside Leptir
  • We do not build hidden profiles

Your control

  • You can edit your logs anytime
  • You can stop using anytime
  • You can request deletion

Also available:

  • Data export as a ZIP of separate CSV files (meals, workouts, weight); signed in: /api/export/csv or Export ZIP on your profile
  • More granular controls (planned)

Security mindset

  • Keep systems simple
  • Avoid unnecessary data collection
  • Limit exposure
  • Build in public, improve continuously
