Frequently asked questions about the Recallme calling app

Short, clear answers.

How much data does a Recallme call use?

About 900 KB for 10 minutes on average, on mobile data or Wi‑Fi. It varies with the network and call quality.

Is it really free?

The app is free to use, with no ads. Your mobile data or Wi‑Fi is still yours to pay for, but a call uses very little.

What about one hour of calling?

About 5.4 MB, from a linear estimate (10 minutes ≈ 900 KB). It is not a guarantee: the network changes the result.

Are my calls encrypted?

Audio is end-to-end encrypted. Call information (who calls whom, and when) goes through our servers.

What is the verification code for?

During a call, a 4-digit code appears. Compare it aloud with the other person: if it matches, nobody is in between.

Which phones does Recallme run on?

Android. An iOS version is planned; no date has been announced.

Can I use Recallme without the app?

Yes, with the “Continue on the web” link. The Android app remains the best experience (full-screen ring, widgets).

Does the phone ring when it is locked?

Yes. The call screen opens full screen, even with the app closed. If you use “Force stop” in Android settings, the system blocks alerts until the next time you open the app.

What if my contact is offline?

They get a missed-call notification as soon as their phone reconnects. You can also send them an SMS the app prepares for you.

How does Recallme find my contacts?

Numbers are hashed before they are sent: the server does not receive your address book in clear text.

How do I block a contact?

Open their page and choose to block them. They can no longer call you.

What if the connection is poor?

A “poor connection” banner appears. Move closer to a Wi‑Fi spot or switch network.

Can I call abroad?

Yes, as long as you and the other person have internet. There is no per-minute rate, but your carrier may bill its data.

How do I delete my account?

In Settings › Privacy and data › Delete my account and my data, or by e-mail. The dedicated page is on politique.recallme.online (in French).
