Most trackers answer the wrong question. They will show a grid of everything you have ever started, then leave you to work out where you had got to. ScreenTrak is built around one answer instead: the next episode you have not seen, per show, ready the moment the app opens. Marking it watched takes one tap, and undoing that takes another.
Anime is the case that breaks this category. Numbering runs absolute where a season-and-episode model expects a grid, and trackers built for Western television quietly mangle it. ScreenTrak treats anime as a first-class case in version one rather than a mapping bolted on afterwards, with spoiler-safe episode groups and season-level totals that do not give away what is ahead.
The architectural decision underneath is about ownership. ScreenTrak assigns its own permanent IDs to every show, season and episode, and treats the metadata provider — TVmaze in version one — as a replaceable adapter behind them. Watch history is tied to ScreenTrak's identifiers, not the provider's, so the catalogue source can change without touching what anyone has recorded. Provider outages degrade search rather than the library.
That principle carries through to the data itself. Export to JSON or CSV is free and generated on demand, with no file left on a server afterwards. Account deletion is self-service and verified against both the database and the auth layer, with the device queue and session cleared alongside — no support ticket, no retention period, no dark pattern in the way. Watch history is never sold and never used for advertising.
