Block spam without giving up your privacy

Many spam blockers ask for your contact list or your call history. NoCall does not upload them: matching against the spam database happens on your device, and we keep only what we need to operate.

An account for the app, your contacts stay on your phone

To use the app you sign in with Apple, Google, Facebook or a code sent to your email. Your contacts are never uploaded and the number calling you is not sent to any server.

On-device matching

The spam database is downloaded to the device and queried locally. Incoming numbers are matched on your phone — they never leave it.

Designed for the GDPR

Your account is used to sync the database and manage your plan. We also keep reports and aggregate statistics, and billing data if you buy Pro. The free plan shows ads.

  • Your contacts are never uploaded
  • Zero call history sent to our servers
  • Anonymous reports, rate-limited and signed
  • EU hosting, ISO-aligned operational practices
  • Full data export and deletion available on request

FAQ

How can lookups work without an account?

We use a privacy-preserving session token signed by your browser. It identifies the device for rate limiting, not the person.

Do you sell aggregated data?

No. Aggregated trends are published openly on /tendencias, but we never sell or license user-level data.

Can I delete everything you have on me?

Yes. Email [email protected] and we'll wipe any device-tied data within 30 days, as required by the GDPR.
