Privacy policy.
Selene keeps your data on your phone. There's no account, no ads, no analytics and no tracking. The one thing that can leave your phone is your email address, and only if you choose to join the newsletter.
Last updated: October 19, 2026 · Selene 3.2.0
In short
- Your birth details, location and settings are stored only on your device
- All astronomy is calculated on your device; Selene needs no internet connection
- No permissions to grant, no GPS, no account
- No ads, analytics, crash reporting or in-app purchases
What Selene stores, and where
Everything below stays in the app's local storage on your phone. None of it is sent to LD Coda or anyone else.
- Birth details (optional): date, time and city of birth, used for your birth Moon, chart angles and houses, progressed Moon, and birth nakshatra and mansion.
- Location for moonrise and moonset: a city you pick from the app's built-in list (it defaults to your birth city). Selene never uses GPS or your device's location.
- Settings: your calculation method, house system, theme and the tab you last opened, and whether you have joined the newsletter.
Positions are calculated on the device with the Astronomy Engine library, and every reading is part of the app.
The newsletter (optional)
If you type your email into "Stay updated" in Settings and tap Join, or join on this website, your address is sent to LD Coda's newsletter service through AWS API Gateway, tagged with where you joined. It is used only for news about LD Coda apps, feature updates and lunar insights. Nothing is sent unless you tap Join. You can leave at any time, or ask us to delete your address at selene@ldcoda.com.
Permissions
Selene asks for no permissions: no location, camera, microphone, contacts, photos, files or notifications. Like every Android app that can go online, it has internet access, which Android grants at install without asking. Selene uses it only for the newsletter signup.
No tracking, ads or analytics
Selene contains no analytics, advertising, crash-reporting, tracking or billing libraries (we checked the 3.1.0 Android build), uses no cookies or fingerprinting, and shows no ads. It has no in-app purchases.
Deleting your data
Open Settings, then Data & Privacy, and tap Clear All Data to wipe everything Selene stored. Uninstalling the app removes it too.
This website
This site sets no cookies and runs no analytics. Its fonts are served from this site. The App Store and Google Play badge images load from Apple's and Google's servers, which see your IP address as any web server does.
- Contact form: handled by Formspree, which receives what you type (name, email, device and message). See the Formspree privacy policy. Contact messages are kept for up to two years.
- Newsletter form: sends your email address to the newsletter service described above.
Children
Selene is suitable for all ages and does not collect personal information. If you believe a child has sent us an email address or a message, write to selene@ldcoda.com and we will delete it.
Your rights
Wherever you live, including the EU (GDPR) and California (CCPA), you can ask what we hold about you and have it deleted. The only things we can hold are a newsletter address or a contact message you sent. We never sell data. LD Coda is the data controller; contact selene@ldcoda.com.
Changes
If this policy changes, we will update this page and the date at the top.
