# F-Droid ## Identification [[F-Droid|F-Droid]] is an open-source Android repository/client; [[TutuApp|Tutu]] is an alternative mobile-app distribution service; [[3C All-in-One Toolbox|3C All-in-One Toolbox]] is a device-management utility. `F-Droid.apk` uses the [[Android Application Package|APK]] package format; the source word `Toolbar` is normalized only outside the quotation to the known product spelling `Toolbox`. ## Notebook evidence - [[Scanned_20260730-1659#PDF page 7 — F-Droid, Tutu, and 3C Android tools|PDF page 7: F-Droid, Tutu, and 3C Android tools]] — F-Droid is an installable catalog and repository ecosystem for free/open-source Android applications, while TutuApp represents a third-party distribution channel and 3C All-in-One Toolbox a device-management utility. F-Droid’s official documentation emphasizes reproducible repository metadata and user-controlled sources. The list reads as a **comparative acquisition surface**: trusted open-source repository, less-governed alternate store, and deep system utility. - [[Scanned_20260730-1659#PDF page 8 — Sideways duplicate of Android-tool list|PDF page 8: Sideways duplicate of Android-tool list]] — This is a physical duplication of page 7, not a new conceptual entry. Its sideways orientation suggests either a scanning-order artifact or deliberate reuse of the page margin. Archival retention matters because duplicated fragments reveal which tool triads were important enough to be recopied or re-photographed. - [[Scanned_20260730-1659#PDF page 25 — Storage Access Framework and open mobile infrastructure map|PDF page 25: Storage Access Framework and open mobile infrastructure map]] — The page sketches an unusually coherent **sovereign-mobile stack**. Android’s Storage Access Framework mediates user-approved document access; Android documentation requires third-party apps to use it for portable storage. F-Droid/APKPure/APKMirror supply software, AOSP supplies the base operating system, Ubuntu Touch/PinePhone/Librem 5 represent alternative mobile platforms and hardware, Firebase supplies backend services, and Tor/OpenVPN/FreedomBox supply privacy and self-hosting. ## Relationships and overlays The source places this record in an evidence cluster with [[3C All-in-One Toolbox|3C All-in-One Toolbox]] · [[Android Application Package|Android Application Package]] · [[Android Open Source Project|Android Open Source Project]] · [[APKMirror|APKMirror]] · [[APKPure|APKPure]] · [[Firebase|Firebase]] · [[FreedomBox|FreedomBox]] · [[Librem 5|Librem 5]] · [[Notebook Duplication|Notebook Duplication]] · [[OpenVPN|OpenVPN]] · [[PinePhone|PinePhone]] · [[Storage Access Framework|Storage Access Framework]] · [[Tor|Tor]] · [[TutuApp|TutuApp]] · [[Ubuntu Touch|Ubuntu Touch]]. The occurrence contributes to the notebook's larger model of [[Identity Continuity|identity continuity]], [[Device Sovereignty|device sovereignty]], and [[Continuity Architecture|continuity architecture]]. ## Evidentiary status and open leads Correct “Toolbar” versus “Toolbox” only in normalized analysis; locate package IDs and installation dates. ## Source - [[Scanned_20260730-1659|Scanned_20260730-1659]] ## Scanned_20260730-1314 overlay [[Scanned_20260730-1314#Scanned_20260730-1314.pdf — PDF page 14|Pages 14 and 39]]: F-Droid appears first in application-source provenance and later beside custom-ROM components, linking software distribution to system-image composition. **Relationship overlay:** [[GitHub]] · [[Android Package]] · [[OmniROM]]. ## Scanned_20260730-1806 overlay [[Scanned_20260730-1806#Page 22 — `Scanned_20260730-1806.pdf`, PDF page 22|Pages 22–27]] use F-Droid as a provenance surface for the oF2pks inspection-tool family: [[apps_Packages Info]], [[Chairlock]], [[kDI Device Info]], and [[ClassyShark3xodus]].
