Privacy Policy

1. Who this policy covers

This policy applies to the Cosmic Day mobile app (iOS and Android), published by Mehdi ("we", "us"). Contact details are on the Support page.

2. Data that stays on your device

When you use Cosmic Day, the app stores the following locally on your device only, using standard on-device storage (Apple's / Android's local app storage). None of it is transmitted to us — we don't operate a server for it, and we can't see it:

• Your birth date, time and place, and anyone else's birth data you choose to add (for people, circles or compatibility)
• Your daily check-ins (mood, tags) and the personal patterns the app derives from them
• People, circles, life events and universe items you add
• App settings, including notification preferences and whether you've added an API key (see §4)

Deleting this data is built into the app: Settings → Your data → Delete my data removes everything immediately. Uninstalling the app also removes it, since nothing is kept anywhere else.

3. Ads (Google AdMob)

Cosmic Day shows banner, native, interstitial and rewarded ads through Google AdMob (the Google Mobile Ads SDK) to keep the app free. To serve and measure ads, Google's SDK can collect and process:

• Advertising identifiers (Android's Advertising ID, or Apple's IDFA if you grant App Tracking Transparency permission)
• IP address and approximate, coarse location derived from it
• Device information (model, OS version, language) and app usage signals relevant to ad delivery

Ads never see your birth chart, check-ins or anything else you enter into Cosmic Day — the app doesn't pass that data to AdMob.

Your consent choices:

• In the European Economic Area and the UK, Google's User Messaging Platform (UMP) shows a consent form before any personalized ad is requested, as required by the IAB Transparency & Consent Framework. You can change your answer anytime in Settings → Privacy & Ads → Ad privacy choices.
• On iOS, the App Tracking Transparency prompt asks permission before IDFA is used for ad personalization. Declining doesn't stop ads — you'll simply see non-personalized ones. You can change this later in your device's Settings → Privacy & Security → Tracking.
• On Android, you can reset or opt out of your Advertising ID in your device's Settings → Google → Ads.

Google's own policies govern what it does with this data: Google Privacy Policy and How Google uses data in ads.

4. Optional AI chat (your own API key)

Cosmic Day's "Ask Your Chart" feature works fully offline by default. If you choose to add your own Anthropic API key in Settings, the app will send your computed astrology facts (planet positions, aspects — never raw birth data) and your chat messages directly from your device to Anthropic's API, so a language model can word the answer. Anthropic is told, by the request itself, never to compute or invent positions — only to phrase what the app already calculated. This only happens if you've added a key; nothing is sent otherwise. See Anthropic's Privacy Policy for how they handle that data.

5. What we don't do

• We don't operate a server that stores your personal data — there isn't one.
• We don't require an account, an email address, or a phone number to use the app.
• We don't sell personal data, and we don't run any analytics or crash-reporting SDK ourselves beyond what AdMob's own SDK inherently collects to serve ads.
• We don't share your birth chart, check-ins or any content you create in the app with any third party.

6. Children's privacy

Cosmic Day is a general-audience app and is not directed at children. We don't knowingly collect personal data from children under 13 (or the minimum age required in your country). If you believe a child has provided data through the app, contact us via the Support page and we'll help you remove it — though since almost everything lives only on the device itself, deleting it locally (Settings → Delete my data) is usually enough.

7. Your rights

Because your data lives on your device, you're always in direct control of it: view it, change it, or delete it any time in the app itself. If you're in the EEA, UK, or a jurisdiction with similar rights (such as under GDPR or CCPA), you also have rights over the data Google's ad SDK processes on Google's own systems — Google's privacy policy explains how to exercise those directly with Google. For anything else, reach us via the Support page.

8. International data transfers

Because Google and (if you enable it) Anthropic operate globally, ad-related data and, if applicable, chat requests may be processed in countries other than your own. Both companies publish their own safeguards for international transfers in the policies linked above.

9. Changes to this policy

If this policy changes, we'll update the date at the top of this page. Continuing to use Cosmic Day after a change means you accept the update.
