MileTracker uses Supabase for auth and cloud storage. Here's why we picked it and what it means for your data.
Why Supabase
- Postgres database — battle-tested, easy to back up
- Row-level security keyed to your user ID
- Predictable, transparent pricing
- No vendor lock-in — it's standard Postgres underneath
What it means for you
Your trip data lives in a Postgres row that only you can read. We back up daily. If you ever ask for an export, we can hand you everything — and if you ask for deletion, we can purge everything.
MileTracker detects every drive in the background, lets you classify business or personal in one tap, and exports an IRS-ready PDF and CSV at tax time. Download MileTracker free on the App Store.
