{"slug": "saracroche-call-and-sms-spam-blocker", "title": "Saracroche (Call and SMS Spam Blocker)", "summary": "Saracroche, a free and open-source call and SMS spam blocker for iOS and Android, filters locally on the device and has blocked all daily telemarketing and AI calls for a user on GrapheneOS. The app, which is GPLv3 and available on F-Droid, uses a local list of roughly 16 million numbers from ARCEP telemarketing ranges and user reports, with no contacts access, ads, or account. The project scopes itself to France, though its design is not France-specific.", "body_md": "Free and open source call and SMS spam blocker for iOS and Android that filters locally on the device.\n\nI have been running this for a few weeks on GrapheneOS and it killed all the daily telemarketing and AI calls, so I figured it was worth bringing here rather than keeping to myself.\n\nA lot of these calls are AI driven now, and some of them are not trying to sell you anything.\n\nThey keep you talking to collect a sample of your voice, and a cloned voice is enough to get consent recorded at a bank for things like direct debits.\n\nIn France we get enough of these calls that picking one up eventually is a matter of time.\n\nGPLv3, sources on Codeberg for both clients, Android build on F-Droid. The GitHub repos are archived mirrors since February 2026 and only point back to Codeberg.\n\nBlocking is local. The lists sit on the device and refresh about once a day, so no lookup leaves the phone per incoming call and it works offline.\n\nThe Android build requests four permissions: network state, internet, foreground service, notifications. No contacts access, no ads, no account.\n\nRoughly 16 million numbers, built from ARCEP allocated telemarketing ranges plus in-app user reports thanks to its great community behind.\n\nReporting a number sends that number and a random install UUID to a server in France.\n\nKnown limits: prefix based blocking does nothing against spoofed mobile numbers, the project scopes itself to France explicitly even though nothing in the design is France specific.\n\nNone currently. In my opinion this would need a new category.\n\nThanks!", "url": "https://wpnews.pro/news/saracroche-call-and-sms-spam-blocker", "canonical_source": "https://discuss.privacyguides.net/t/saracroche-call-and-sms-spam-blocker/39891#post_1", "published_at": "2026-08-14 06:15:48+00:00", "updated_at": "2026-08-14 06:18:54.982347+00:00", "lang": "en", "topics": ["ai-products", "ai-tools"], "entities": ["Saracroche", "GrapheneOS", "F-Droid", "Codeberg", "GitHub", "ARCEP"], "alternates": {"html": "https://wpnews.pro/news/saracroche-call-and-sms-spam-blocker", "markdown": "https://wpnews.pro/news/saracroche-call-and-sms-spam-blocker.md", "text": "https://wpnews.pro/news/saracroche-call-and-sms-spam-blocker.txt", "jsonld": "https://wpnews.pro/news/saracroche-call-and-sms-spam-blocker.jsonld"}}
