Privacy Policy

Who we are

SkyChrono is run from Norway. “We” in this policy means SkyChrono, the data controller for the personal data described here.

Please send any privacy question to privacy@skychrono.com.

What we handle

SkyChrono has no accounts and keeps no personal data on its servers. To show your sky it handles only this:

• The place you choose — its coordinates go to our server to find the local time zone, the Sun and Moon tables and, for nights within about ten days, the cloud forecast. They are not stored.
• City search — the text you type goes through our server to a place-name service that finds matching cities.
• Approximate location — to open on a sky near you, we read the approximate city Cloudflare attaches to each request from your network address. This happens on our own infrastructure, is rounded to about 1 km and is not stored. You can choose another place at any time.
• Your precise location (optional) — only if you choose “Your location” and allow it in your browser. The coordinates are used as above, are not stored, and never become your remembered home city.
• Camera and motion sensors (optional) — “Point at the sky” uses your phone’s direction and tilt and, if you allow it, the back camera. Readings and camera frames stay in your browser: they are never uploaded or stored, and they stop when the view closes or the page is hidden.
• Browser storage — recent and favourite places, the last city you chose, your night list, saved plans and display settings are kept in your browser’s local storage. They stay on your device and are not sent to us. We use no cookies.
• Shared links — a link you share contains the place, time and view it shows. Anyone with the link can open it.
• Calendar files — “Add to calendar” creates a file on your device. Nothing is sent to us.
• Technical logs — Cloudflare, our hosting provider, records standard request details (such as IP address, browser and time) to keep the service secure and running. We use no analytics, advertising or tracking.

Why we are allowed to process the data

Under the GDPR we need a legal basis for each use:

• Showing the sky for the place you choose, city search, the approximate starting place and the cloud forecast — legitimate interest (Art. 6(1)(f)) in providing the service you ask for, with as little data as possible.
• Precise location, camera and motion sensors — used only when you choose them and allow them in your browser. You can withdraw at any time by changing the browser permission.
• Technical logs — legitimate interest in keeping the service secure and running.

Who we share data with

• Cloudflare, Inc. — hosting and content delivery, as our processor under a data processing agreement (GDPR Art. 28).
• MET Norway (the Norwegian Meteorological Institute) — receives the chosen place’s coordinates, rounded to about 1 km, and returns the cloud forecast.
• Open-Meteo — receives the text you type in the city search, or the number of a city you chose, and returns place names from GeoNames.

Requests to MET Norway and Open-Meteo come from our server, so your IP address is not passed on. We don’t sell your data and we don’t share it with advertisers.

International data transfers

SkyChrono runs on Cloudflare’s global network, so requests may pass through locations outside the EU/EEA. Cloudflare is a US company; transfers are covered by the EU Standard Contractual Clauses (SCCs). MET Norway is in Norway.

How long we keep data

• On our servers — no personal data is kept. Forecast answers are cached for up to an hour by rounded place, and city-search answers may be cached briefly, with no link to you.
• Technical logs — kept by Cloudflare for a short time for security and operation.
• Browser storage — until you clear it yourself, by clearing this site’s data in your browser.

Your rights

Wherever you live, you can ask us to:

• Show you a copy of your data (right of access).
• Correct mistakes (right to rectification).
• Delete your data (right to erasure).
• Move your data to another service (right to data portability).
• Stop or limit processing (right to restriction or objection).

Because SkyChrono has no accounts and keeps nothing about you on its servers, almost all of your data is in your own browser, where you can delete it by clearing this site’s data. For any request, email privacy@skychrono.com; we reply within one month. If you live in the EU/EEA you can also complain to your local data protection authority (in Norway: Datatilsynet, datatilsynet.no). UK users can complain to the ICO (ico.org.uk).

California residents (CCPA / CPRA)

If you live in California, you have the right to know what categories of personal information we handle and why, the right to deletion, and the right not to be discriminated against for using your rights. We do not sell personal information and we do not share it for cross-context behavioural advertising. To use any of these rights, email privacy@skychrono.com.

Children

SkyChrono needs no account and collects no personal data from anyone, children included. If you believe a child has sent us personal information by email, write to privacy@skychrono.com and we will delete it.

Security

All traffic uses HTTPS/TLS. We keep no personal data on our servers, and coordinates are rounded before they leave them. No system is perfectly secure, but if we discover a personal data breach that affects you, we notify the Norwegian Data Protection Authority within 72 hours and notify you where required and possible.

Changes and contact

We may update this policy as the service evolves; the date at the top shows the latest version. Significant changes will be announced on the site. For privacy questions, email privacy@skychrono.com.
