It's yours.
No asterisks.
Most fitness apps gate export behind a Pro tier, a CSV with three columns, or a JSON dump you can't actually read. flexRep is built on the opposite stance: data portability is a product pillar, not a checkbox feature. Export is free now and forever.
11 columns. Every set.
One row per set. ISO timestamps. Weight in kilograms — the canonical unit. RPE half-steps. The notes field carries whatever you typed in the app.
Full schema. Plain shape.
Workouts → ExercisePerformances → SetEntries. UUIDs everywhere. Soft deletes filtered out. Checksum at the top so you can verify nothing changed in transit.
The same schema docs/SCHEMA.md publishes for developers. No mystery fields. Nothing renamed for "branding". If you import a flexRep export into a spreadsheet six years from now, every field will still make sense.

}What 'data ownership' actually means here.
Free, forever.
CSV and JSON export are in the free tier. No subscription. No "Pro export" upsell. If you can log a set, you can pull every set.
Every column, every set.
No "summary mode". No "Pro adds RPE column". Every row carries weight, reps, RPE, RIR, set type, equipment, group, notes, timestamp.
No vendor lock-in.
Generic CSV format. Plain JSON schema. .flexrep bundles are zipped JSON with a SHA-256 checksum file. Any other tool can read your data.
Reversible imports.
Every import tags entities with a UUID batch ID. Revert wipes the batch and leaves your native data untouched. No "I shouldn't have imported that" panic.
Two-way HealthKit.
flexRep writes per-set metadata to Apple Health. Body weight syncs both ways. If you delete the app, your data already lives in Health.
On-device by default.
No analytics SDKs, no ad networks, no telemetry. Foundation Models runs locally. iCloud sync is opt-in.
