Boost for Lemmy keeps sessions, drafts and media cache in private Android storage under its developer package.
Last updated
Boost for Lemmy is Android only, with private databases for sessions, drafts and media cache under the developer package. The ID embeds the developer name, which sets it apart from similarly named Reddit clients in guides and file managers. Instance follows and blocks stay server side, so local files cover session and UI state rather than the timeline itself.
For stale thumbnails, use Settings Apps Storage and choose Clear Cache, which leaves logins alone. Full Clear Storage logs the app out and drops local drafts, so keep that choice for cases where a fresh login is planned. The in-app backup preserves theme and filter prefs across reinstalls, while accounts always sign back in per instance.
