🛡️ Defending Mobile Privacy.

Most stock dialers and caller-ID apps today have become data harvesters—monetizing your call logs, uploading your personal address books, and injecting intrusive ads.

Secure Dialer was built on an uncompromising principle: Zero internet permissions. Zero analytics. 100% on-device privacy.

💡 Where Does Sponsorship Money Go?

Because Secure Dialer is completely offline, we don't have cloud server bills to pay. Instead, 100% of your sponsorship directly funds:

  1. 📱 Physical Android Test Devices: Testing native Telecom Service, dual-SIM routing, and audio state across fragmented OEM skins (Samsung One UI, Google Pixel, Xiaomi HyperOS, GrapheneOS, LineageOS) from Android 7 through Android 16.
  2. 🔒 Security & Cryptographic Maintenance: Keeping our local SQLCipher AES-256 encrypted database robust, fast, and up-to-date.
  3. ⚡ Independent Full-Time Maintenance: Ensuring bugs are fixed rapidly and new releases ship without ever needing ads, venture capital, or paid feature paywalls.

❤️ Our Promise to You

  • Never any ads or telemetry: We will never compromise user trust.
  • Never paywalled core features: The entire dialer and contacts engine stays 100% free and open source.
  • Zero-fee FOSS support: GitHub Sponsors takes 0% fees on personal contributions, so every dollar directly backs the project.

Whether you choose a $X/month pledge or a one-time donation, thank you for supporting open, tracker-free android dialer.

@Secure-Phone-apps

My first milestone is welcoming 10 dedicated privacy oriented friends to the Secure Dialer community. Reaching this goal proves that a 100% offline, tracker-free dialer truly matters to real people, and this motivation will keep me going. Your support directly funds not just this dialer, but also boosts my confidence and belief of working on essential apps to be 100% open, telemetry free, boosting privacy of all of us. Being one of our first 10 sponsors lays the foundation for independent, private calling. Thank you for believing in us!
