Privacy policy
Last updated November 14, 2026
Nana is an alarm that only stops when you say a phrase back in another language. This policy explains what Nana collects, why, and how to get rid of it. Short version: no ads, no tracking, no selling your data, and your alarms stay on your phone.
What stays on your phone
Your alarms, their times and repeat days, your settings, your favourite phrases, the crew members you've blocked and the phrases you've downloaded are stored only on your device. We never see them.
The microphone and speech recognition
Nana uses the microphone only while you say a phrase back, or while you record a phrase for Nana's crew.
To check your words, Nana uses your phone's built-in speech recognition (Apple on iPhone, Google on Android). When your phone can't do this on the device, Apple or Google may process the audio on their servers under their own privacy policies. Nana doesn't keep or upload these attempts.
To check your accent, Nana compares your voice with the recording on your phone, using a speech model that's downloaded once from Hugging Face. Your voice doesn't leave your phone for this.
Your anonymous account
When you first open Nana, it creates an anonymous account for you: a random ID with no name, email or phone number. It's used to send the usage data below and, if you join the crew, to link you to your crew name and recordings.
Usage and error data
Unless you turn off "Share usage data" in the You tab, Nana sends, linked to your anonymous ID:
• Say-it-back results: which phrase and language, the scores, whether you passed, and the text the speech recognizer heard. No audio.
• Alarm results: that an alarm rang, how long it took you to stop it and how many tries. Not your alarm times.
• Errors: what went wrong, your platform (iOS or Android), its version and Nana's version.
We use this only to make the matching fairer and to fix bugs.
Nana's crew (optional)
If you join the crew, we store the crew name you choose. If you record a phrase, we store the recording, the phrase text and translation you typed, what the speech recognizer heard and how well it matched.
A person on the Nana team listens to every recording before it's published. Approved recordings are played to other Nana users and can be downloaded by anyone who has the app. Recordings are kept in storage that can be read by anyone who has the exact link.
If you report a phrase, we store your report. If we block one of your phrases, we store the reason, and you can see it in My phrases.
Who processes it
Supabase hosts Nana's database and recordings. Apple and Google provide speech recognition. Hugging Face hosts the speech model your phone downloads. We don't use advertising or third-party analytics SDKs, we don't track you across other apps or websites, and we never sell your data.
Keeping and deleting your data
We keep this data until you delete it, or until it's no longer useful for improving Nana.
To delete everything, go to You → Delete my data. This removes your anonymous account, crew name, recordings, phrases, reports and usage data from our servers. Your alarms on your phone stay until you delete the app. You can also email us and we'll do it for you.
Age
Nana is for people aged 17 and over. It includes slang, crude humour and references to drinking. We don't knowingly collect data from anyone under 17. If you think a child has used Nana, email us and we'll delete their data.
Your rights
Depending on where you live, you may have the right to see, correct, export or delete your data, or to object to how it's used. Email us and we'll help. Since your account is anonymous, we may ask you to send the request from the app so we can find your data.
Security
Data is sent over encrypted connections. Each account can only read its own data, and only the Nana team can see usage data and recordings waiting for review.
Changes
If this policy changes, we'll update the date at the top. If a change matters, we'll also tell you in the app.
