Privacy policy

Last updated: November 11, 2026

Sayword is an app for practicing the pronunciation of one word a day. This policy explains what data it uses, why, and how to delete it. The idea is simple: we use the minimum the app needs to work, and we never sell or share your data for advertising.

Without an account

You can use Sayword without an account. Your streak, your words and your settings (languages, reminder, sounds) then stay only on your phone.

Your voice

When you record a word, the recording travels encrypted to our server and from there to Microsoft Azure AI Speech, which compares it with the word and returns a score. We do not keep the recording: it is used to compute the score and then discarded. Microsoft processes it as our service provider, under its Azure privacy terms. The microphone is only used while you record.

To let you hear how a word sounds, we ask Azure to read it aloud. That only sends the text of the word, nothing about you.

On the website

The website sayword.app also lets you try the word of the day. The recording goes to the same service, is scored and is not stored. To limit tries per day we count how many each IP address used, only in memory and until the next day. The site uses no cookies: it only remembers in your browser how many tries you used today.

If you create an account

An account is optional and keeps your streak if you change phones. You sign in with Google (or Apple), and we store:

• Your name and email, as Google or Apple share them, and your account id with that service.
• Your progress: streak, best streak and words practiced.
• Your settings: language you learn, explanation language, reminder time and sounds.
• A hashed version of the session code of each phone you signed in on.

We never receive your Google or Apple password.

Anonymous sound statistics

Each time the app scores a recording, we add it to anonymous counters per sound: how many times it came out right, nearly right or wrong. The counters are grouped by the language you practice, the explanation language, the country set on your phone, and per week. They are kept without your account or IP address or the exact time, so they cannot be linked to you. They help us learn which sounds are hardest (for example, for Spanish speakers). These anonymous statistics hold nothing about you, so they are not deleted with your account.

Technical data

Like any server, ours logs technical data for each request (IP address, time and what was asked) for security and to fix errors. It is kept for a short time and not used to identify you. Traffic goes through Cloudflare, which protects the server.

Reminders

Reminders are notifications scheduled by your own phone. Our server sends nothing for them.

What we don't do

• We don't sell your data.
• We don't show ads or use analytics or tracking tools (the anonymous sound statistics above are our own and identify no one).
• We don't share your data with anyone other than the providers above, and only so the app works.

If we add subscriptions or ads in the future, we will update this policy first.

Where it is stored

On our own server, in a database on an encrypted disk. Everything travels encrypted (HTTPS). Daily backups are deleted after 14 days.

Deleting your account

In the app: Settings > Delete account. Everything we store about you is deleted right away (the anonymous sound statistics stay, since they hold nothing about you); backups disappear on their own within 14 days. If you no longer have the app, follow the steps on this page.

Your rights

You can ask us to see, correct or delete your data at any time by writing to us. We answer within 30 days.

Children

Sayword is not meant for children under 13, and we do not knowingly collect their data.

Changes and contact

If we change this policy, we update the date above and, for important changes, tell you in the app. Questions: hola@sayword.app
