Privacy Policy

Last updated: April 13, 2026

Meteogram is designed to use as little personal data as possible. The app does not require an account, does not sell personal data, and keeps analytics optional.

1. Who we are

Meteogram is operated by the independent developer of Meteogram ("we", "us", "our"). For privacy questions or to exercise your data protection rights, contact mpenapps@protonmail.com.

2. Scope of this policy

This policy explains how Meteogram processes personal data when you use the app, website-hosted legal pages, and related services. It is intended to satisfy GDPR transparency requirements, including for users in Greece.

3. Data we process

Depending on how you use the app, we may process the following categories of data:

Location data - your device coordinates when you allow location access, so we can fetch forecasts and optionally refresh them in the background.
Search and place data - the place query you type and the selected place label, coordinates, and country code needed to show forecasts.
Local settings and cached content - pinned location, recent searches, preferences, cached forecasts, and related metadata stored on your device.
Purchase status - subscription or entitlement status provided through RevenueCat and the relevant app store.
Optional analytics data - if you enable analytics, event name, app platform, app version, trigger, limited counters or durations, and a pseudonymous app-install identifier.

4. Data we do not intentionally collect

Your name, email address, or account profile in the app
Advertising identifiers such as IDFA or GAID
Contacts, photos, messages, or similar device content
Payment card details, which are handled by Apple or Google

5. Why we process data and our legal bases

To provide weather forecasts you request - legal basis: performance of a contract under Article 6(1)(b) GDPR.
To remember your settings and chosen locations - legal basis: performance of a contract under Article 6(1)(b) GDPR.
To manage subscriptions and restore purchases - legal basis: performance of a contract under Article 6(1)(b) GDPR.
To run optional analytics - legal basis: consent under Article 6(1)(a) GDPR.
To maintain, secure, and improve the service - legal basis: legitimate interests under Article 6(1)(f) GDPR.

6. Location permissions

If you grant location access, Meteogram uses your device coordinates to retrieve weather data for your current location. If you grant background location access, the app may refresh weather data in the background. You can also use Meteogram without device location by searching for a place manually.

7. Optional analytics

Analytics are off by default on first launch. You can enable or disable them at any time in the app settings.

If enabled, the app sends limited pseudonymous analytics events to TelemetryDeck. We do not intentionally send your name, email address, advertising ID, payment details, or precise search text in analytics events.

8. Third-party recipients and processors

Apple WeatherKit - provides weather data. See Apple's privacy policy.
Nominatim / OpenStreetMap - used for place search and some reverse geocoding. See the OpenStreetMap Foundation privacy policy.
RevenueCat - used to manage subscriptions and entitlement state. See RevenueCat's privacy policy.
Apple App Store / Google Play - process purchases, subscriptions, billing, and refunds under their own terms and privacy notices.
TelemetryDeck - processes optional analytics on our behalf when you opt in. See TelemetryDeck's privacy policy.

9. International transfers

Some recipients listed above may process data outside the European Economic Area. Where applicable, transfers rely on the provider's lawful transfer mechanism described in that provider's documentation.

10. Storage and retention

On-device data - remains on your device until overwritten, cleared, or removed when you uninstall the app.
Location and search requests sent to third parties - are retained according to the receiving provider's own practices.
RevenueCat purchase data - is retained according to RevenueCat's and the app store's policies.
Optional analytics - are retained in TelemetryDeck for the period configured there, after which they are deleted or aggregated.

11. Your GDPR rights

Subject to the conditions and limits in applicable law, you may have rights of access, rectification, erasure, restriction, objection, portability, and withdrawal of consent where applicable. To exercise these rights, contact mpenapps@protonmail.com.

12. Complaints

If you are in the EU, you have the right to lodge a complaint with your local supervisory authority. If you are in Greece, you can contact the Hellenic Data Protection Authority at dpa.gr.

13. Children's privacy

Meteogram is not directed to children under 13, and we do not knowingly collect personal data from children through the app.

14. Changes to this policy

We may update this policy from time to time. If we make material changes, we will update the date at the top of this page.
