Privacy policy

Last updated: 10 November 2026

Olvy is an app that tells you what to wear for the weather. It is built to work without knowing who you are. This policy explains exactly what data is involved.

Who is responsible

Good Days OÜ (registry code 12627359), Estonia, is the controller of the data described here. Contact: support@olvy.app.

What stays on your phone

• People you add — names (or nicknames), age group, usual activity and your “too cold / too hot” adjustments.
• Saved places — their names and coordinates.
• Settings — language and widget options.

This information is stored only on your device. There is no account, and we never receive names or ages. Deleting the app deletes it.

Location

To get a forecast, the app sends approximate coordinates (rounded to about 1 km on your phone) to our server. The server rounds them further to a grid cell of about 5 km and requests the forecast for that cell from our weather provider. Coordinates are not stored, not linked to you, and are not written to our server logs. The app asks only for approximate (“coarse”) location permission; you can instead search for a place by name.

Weather data providers

Forecasts, marine data and official weather warnings come from WeatherAPI.com. They receive only the rounded grid cell, not any information about you. Warning titles may be translated into your language by an AI translation service (xAI); only the warning text and the region name are sent.

Anonymous usage statistics

To understand how Olvy is used and which version people run, the app sends anonymous usage events to our own analytics server (Matomo, hosted by us in the EU):

• a random install ID generated on your phone (not linked to your name, email, advertising ID or Google account);
• app version, screen opens, and actions such as switching activity, switching places or adding the widget;
• your IP address is shortened (the last two parts are removed) by our server before it reaches the analytics system; the widget sends no IP at all.

No cookies, no advertising IDs, no third-party trackers, no ads. Statistics are never sold or shared.

Server logs

Like any website, our web server keeps standard request logs (IP address, time, requested page, app/browser version) for security and troubleshooting. They do not contain your coordinates or profiles and are deleted automatically after 14 days.

Purchases

If you buy the full version, payment is handled entirely by Google Play. We only receive confirmation that the purchase is valid — never your payment details.

Children

Olvy is made for parents and other adults. It is not directed at children, and we do not knowingly collect data from children. Information about children that parents enter (such as a name and age group) stays on the parent’s phone.

Your rights

Under the GDPR you can ask us about any data we hold, and ask to correct or delete it. Because we don’t know who you are, the analytics data can only be linked to you through the random install ID shown nowhere in the app — in practice, uninstalling Olvy ends all data collection. Write to support@olvy.app with any question. You can also contact the Estonian Data Protection Inspectorate (aki.ee).

Changes

If this policy changes, the new version will be published on this page with a new date.
