To add it later, create a new key with that permission and replace the old one in the app. Settings shows which permissions your key currently has.Civitai limits comments to roughly 10 per hour. The app only posts when you click THANKS.<h3 id="privacy">Privacy</h3>- Your API key is stored in Windows Credential Manager and never reaches the app interface.- No telemetry, no analytics, no automatic updater, and no browser or cookie access.- The app talks only to Civitai. Preference backups never contain your API key.<h3 id="open-source">Open source</h3>The full source is public so you can read exactly what it does. If I ever stop maintaining it, anyone can inspect the code or adapt it to future Civitai API changes.I built this tool because I needed it myself. Feedback is welcome.

CivitAI Companion

Civitai Companion 1.0.28Windows 10/11 x64.Fixed<ul><li>Sync failing with "Civitai returned an unsupported response": Civitai changed the paging cursor of the notification list (it is now <code>date|id</code>). The app sent it in the old format and the server refused the second page, so every sync failed. Paging now uses the new format.</li><li>Switching or removing the API key while a sync is running can no longer write the previous account's data back; Buzz transactions of a previous account are no longer shown after an account change, and a failed Buzz request can be retried with "Try again". (Contribution by CerebralDev.)</li></ul>Faster refresh<ul><li>Missing thumbnails are looked up in parallel, at most once every 5 minutes per notification and for at most 4 seconds, so they no longer slow down every refresh.</li><li>At most 5 notifications of disabled groups are marked read per sync (was 100), stopping at the first failure; a sync is aborted after 30 seconds; manual refreshes within 5 seconds of a successful sync are merged into one.</li></ul>Security<ul><li>Updated Vite and the locked Rust network dependencies (rustls, rustls-webpki, webpki-roots, tokio, quinn-proto) to pick up published security fixes. (Contribution by CerebralDev.)</li><li>A single app instance only; THANKS opt-in is now also enforced in the backend; API redirects are validated.</li></ul>
