WHAT THE POLICIES SAY

Feeder is a free, open-source RSS/Atom/JSONFeed reader for Android, created in 2014 and maintained by a single named developer, Jonas Kalderstam ("spacecowboy", publishing as NoNonsenseApps from Lund, Sweden), with community contributors; the code is published under GPLv3 on GitHub and the app is distributed via F-Droid, Google Play and signed GitHub releases. Caveats: because there is no intermediary, the app fetches feeds, images and full-text articles directly from each publisher's server (so publishers see the device's IP and a Feeder user-agent); an opt-in AI-summary/translation feature sends article text to a user-supplied OpenAI-compatible, Azure or DeepL API; the project is a single-maintainer effort with no legal entity and no formal third-party audit. No breach, incident or regulatory action involving Feeder was found in this research.

COLLECTION

Feeder's README states the app does not sync with the usual remote backends, so no account registration of any kind is necessary, and that it runs locally on the device; the same README publishes the SHA-256 fingerprint of the key used to sign GitHub-released APKs.

COLLECTION

The developer's privacy policy page for NoNonsenseApps (linked from the Google Play listing as Feeder's privacy policy) consists of a single statement that no user data is collected in any way; it does not enumerate data types, retention or contact procedures.

[2026-08-04] · COLLECTION

The Google Play listing's developer-provided Data safety section for Feeder (updated Aug 4, 2026) declares 'No data collected' and 'No data shared with third parties'; Play notes this information is supplied by the developer and may change over time.

OWNERSHIP TRANSPARENCY

Feeder's full source code is published under the GNU General Public License version 3, allowing anyone to inspect, build or fork the shipping application rather than relying on the developer's description of it.

OWNERSHIP TRANSPARENCY

Privacy Guides lists Feeder among its recommended news-aggregator clients, a category whose stated criteria require the software to be open source and to operate locally rather than as a cloud service.

privacyguides.org ↗

OWNERSHIP TRANSPARENCY

The repository's FUNDING.yml lists GitHub Sponsors (user 'spacecowboy') and Ko-fi as the project's only funding channels; no institutional grant, foundation or commercial backer is declared, and no funding amounts are published.

[2026-08-04] · OWNERSHIP TRANSPARENCY

The Google Play listing identifies Feeder's developer as an individual, Jonas Hector Kalderstam, publishing under the NoNonsenseApps name with a Swedish postal address and a nononsenseapps.com support email — no company, foundation or association is named.

SHARING

Feeder's in-app 'AI and translation' settings let a user configure an API key for an OpenAI-compatible provider, Azure OpenAI or DeepL; when enabled, article text is sent to that third-party service for summarisation or translation under the provider's own terms — an opt-in, user-controlled path by which reading content leaves the device (the settings note the integration is 'Compatible with many AI providers, but not all').

[2026-08-04] · SHARING

Because Feeder has no intermediary sync service, it requests feeds, images and full-text articles directly from each publisher's server; the changelog records the app adding its own User-Agent header to HTTP requests (v1.8.29) and shipping a Readability-based 'fetch full text' feature that downloads the article page itself, so publishers see the device's IP address and request pattern for every subscribed feed.

[2026-08-05] · TRACK RECORD

F-Droid builds and signs Feeder from the published source tarball for each version, giving independent build-from-source verification of the distributed binary; no third-party security audit, transparency report, bug-bounty programme, breach or regulatory action involving Feeder was found in this research.

[2026-08-04] · TRACKING TECH

Feeder's changelog documents privacy-protective engineering: v2.20.0 (May 2026) added stripping of tracking parameters from URLs before they are opened, and v1.6.2 (2018) blocked cookies in the in-app WebView; the same changelog notes an earlier crash-report-by-email feature was removed in v2.9.0.

[2026-08-05] · TRACKING TECH

The F-Droid listing for Feeder (v2.22.0, added Aug 5, 2026) shows no anti-feature flags (F-Droid's markers for tracking, non-free network services or ads), credits the author as 'Space Cowboy' under GPLv3 with a ko-fi donation link, and lists the app's permissions — network state, foreground service, full network access, notifications, shared-storage read/write, run at startup and wake lock — all consistent with feed syncing and OPML import/export.
