Privacy Policy
This policy explains what information Artemis Mission Tracker (“the App”), the Artemis Briefing newsletter and the website artemistracker.app process, why, and what your rights are. We keep data collection to a minimum: the App has no user accounts and does not ask for your name or contact details.
Who is responsible
The data controller is Orbital Momentum AS, org. no. 937 615 094, Dalsveien 54B, 0775 Oslo, Norway. Contact: support@orbitalmomentum.app.
On October 1, 2026, ownership of the App was transferred from Bit Factory AS to Orbital Momentum AS. Nothing about how your data is handled changed as a result.
What we process
| Data | Why | Service |
|---|---|---|
| Anonymous usage statistics: app opens, features used, device type, OS version, approximate country (from IP address) | To understand how the App is used and improve it | Google Firebase Analytics |
| Crash and performance data | To find and fix bugs | Google Firebase |
| Push notification token (a random device identifier) | To send the notifications you have turned on | Firebase Cloud Messaging and Apple Push Notification service |
| Anonymous app user ID and purchase history (product, date, price, country) | To unlock Artemis+ and keep your subscription working across reinstalls | RevenueCat |
| Email address, if you sign up for the newsletter | To send you Artemis Briefing | Our newsletter provider |
| Aggregate page views on artemistracker.app, without cookies | To see which pages are read | Cloudflare Web Analytics |
Payments are handled entirely by Apple and Google. We never see your name, card details or Apple ID / Google account.
Settings such as units and notification preferences are stored only on your device.
What we do not do
- We do not show ads and do not use advertising identifiers (IDFA).
- We do not sell or share your data for marketing.
- We do not track you across other apps or websites.
Public data sources
To show mission data, the App fetches public information from sources such as NASA APIs, NASA AROW, Launch Library 2, the Community Orbit API, RSS feeds and GitHub. These requests do not include personal data, but the providers may see your device’s IP address, as with any internet request.
Legal basis
Under the GDPR we rely on performance of a contract to deliver your subscription and the notifications you ask for, consent for the newsletter and push notifications (you can withdraw it at any time), and our legitimate interest in anonymous statistics that help us improve the App.
How long we keep data
- Analytics data: up to 14 months, then deleted automatically by Firebase.
- Purchase records: as long as needed for your subscription and as required by Norwegian bookkeeping law (up to 5 years).
- Newsletter: until you unsubscribe.
- Push tokens: until you turn off notifications or delete the App.
Transfers outside the EEA
Google, RevenueCat and Cloudflare may process data in the United States. These transfers are covered by the EU–US Data Privacy Framework and/or the European Commission’s standard contractual clauses.
Your rights
You can ask for access to, correction or deletion of your data, object to processing, or ask for data portability. Because the App does not know who you are, we may need some help from you to find your data, for example the email address you use for the newsletter or the date of a purchase. Unsubscribe from the newsletter with the link in any email, and turn off notifications in your iPhone or Android settings.
If you think we handle your data incorrectly, you can complain to the Norwegian Data Protection Authority (Datatilsynet).
Children
The App is suitable for all ages and does not knowingly collect personal information from children under 13.
Changes
We will post any changes on this page and update the date at the top.
