LiftShift has one canonical hosted instance:

• Canonical domain: https://liftshift.app

Deployments on any other domain are unofficial. Unofficial deployments may be modified and may not follow the same security practices. Do not assume an unofficial deployment is trustworthy with any credentials.

If you run a modified version for users to interact with over a network, the AGPL requires making the Corresponding Source for the running version available to those users (see AGPL §13).

Public deployments must include visible attribution to the upstream project.

Minimum acceptable attribution:

• Link to official site: https://liftshift.app
• Source link: a publicly accessible link to the Corresponding Source for the exact version running

Attribution must be reasonably discoverable during normal use (for example: footer, About modal, or Settings). Removing, hiding, or obscuring attribution is treated as non-compliance.

By submitting a contribution (code, documentation, or any other material) to this repository, you agree that:

• Your contribution is provided under AGPL-3.0 terms for inclusion in this project.
• You have the right to submit the contribution and it does not contain confidential information.

1. Select your platform (Hevy / Strong)
2. Hevy: Choose your body type + weight unit, then Continue to login/sync (or import CSV). / Strong: Choose body type + unit, then import CSV
3. Explore your analytics across Dashboard, Exercises, and History tabs
4. Get insights with real-time feedback and flexible filtering

Strong CSV imports support common export variants, including:

• Semicolon-delimited (;) files with quoted fields
• Unit-suffixed headers like Weight (kg) and Distance (meters)

If you see this error:

"We detected a Hevy workout CSV, but couldn't parse the workout dates. This usually happens when the Hevy export language isn't English. Please switch Hevy app language to English, export again, and re-upload."

Do the following:

1. Switch your Hevy app language to English
2. Export your workout CSV again
3. Re-upload it to LiftShift
