@kevincador can you look at this?

Hi @mfederowicz, thanks for the PR!

Before we merge, please read our API Use Policy and confirm here that trakt-sync follows it. From a quick look it fits the "personal tool for your own data" use case, which is great.

A few things we'd like also like to be clarified:

• Credential storage - token.json and the settings file are written with 0644. It would make sense to use 0600 (cli/token.go, cli/device.go, cfg/options.go) instead, right?
• Verbose output - -v prints the full Authorization bearer token. Please mask it or leave it out.
• Headers - str/headers.go defines User-Agent and trakt-api-version, but requestSetHeaders only sends Authorization and trakt-api-key. Could you send all required headers with a User-Agent that names trakt-sync and its version (for example trakt-sync/1.19.1)?
• Intended use - please add a short note to the README that trakt-sync is for managing and exporting your own Trakt data, and that it must not be used to bulk-collect public data (lists, comments, ratings) or to feed other services. The paging options make that possible, so it's worth saying explicitly.

One more thing: this page lists libraries, and trakt-sync's client sits under internal/, so other Go projects can't import it. Would you like to expose it as a public package, or should we describe the entry as a CLI tool?

Once those are sorted and you've confirmed compliance, we'll be happy to merge.

Thanks again!

ok @kevincador i read that api use policy, and added sugested notes in Readme.md, all sugested changes are deployed few minutes ago, you can check on releases: https://github.com/mfederowicz/trakt-sync/releases

Please list trakt-sync as a CLI tool; the client stays internal for now (maybe in future we change that).

Thanks @mfederowicz, that was quick! I checked v1.20.0 and v1.21.0 and everything we asked for is in.

About the listing: since v1.21.0 moved the client into the public trakt package, it is a proper Go library now, so we'll keep it on the libraries page as it is. One small suggestion for library users: the default User-Agent is trakt-sync-go. It might be worth saying in the package docs that apps should set their own with WithUserAgent, as your README example already does.

Merging this now. Thanks again for the contribution!
