Privacy Policy — Celestial Grimoire

Effective date: September 13, 2026  ·  Applies to the Celestial Grimoire app for Android, Windows, and Web, on every distribution channel (direct website download, Google Play, and the web app).

Celestial Grimoire ("the app") is developed by Niagara Indie Apps (G Thompson) ("we", "us"). This policy explains what information the app handles, where it goes, and the choices you have. We wrote it to describe exactly what the app actually does — not a generic template — because that is the standard we hold the app itself to.

Local-first No account required No ads No analytics or trackers No data sold or shared

In short: everything you enter into Celestial Grimoire — your birth details, journal entries, favorites, and settings — is stored only on your own device. We do not operate a server that receives or stores your personal data, and the app contains no advertising or analytics software.

1. Information the app stores, and where

All of the following is stored locally in the app's own database on your device, using standard local storage (SQLite via the Drift library). None of it is transmitted to us, to an app server, or to any third party as part of normal app use.

InformationWhy the app collects it
Name or display name, birth date, birth time (or "unknown"), birthplace, time zone, optional birth notes Required to calculate your natal chart, Daily Cards, and astrological placements. This is the core purpose of the app.
Current location (optional, entered as a place name — not GPS) Used only if you enable sunrise-based Daily Card reveal timing.
Journal entries, favorites, collected Daily Cards Your personal records within the app.
Compatibility/synastry profiles you create for other people (name, birth date/time/place) Lets you compare charts. Stored the same way as your own profile — locally only, never uploaded anywhere.
App settings (house system, notification preferences, theme, etc.) Remembers your preferences between sessions.

2. The one feature that does use the internet

When you search for a birthplace or current-location name during onboarding or when adding a compatibility profile, the text you type is sent to your device's built-in place-lookup service (for example, Google's location services on Android or Apple's on iOS/macOS) so it can be turned into map coordinates. This is a standard operating-system feature the app calls into — it is not our server, and we never see or receive that search text. It only happens when you actively search for a place; the app does not otherwise access your device's location or GPS, and does not request location permission.

3. Notifications

Daily Card, Full Moon/New Moon, and journal-reminder notifications are scheduled and shown entirely on your device using your device's local notification system. No push-notification server is involved, and no notification content is sent anywhere.

4. Sharing a Daily Card

If you tap Share on a Daily Card, the app generates an image on your device and hands it to your operating system's normal share sheet — the same mechanism any app uses to share a photo. Where that image goes next is entirely your choice (a messaging app, social media, saving it, etc.). We never receive a copy. The shareable image never includes your exact birth date, birth time, birthplace, or private journal content, regardless of which share option you choose.

5. What the app does not do

6. Your choices and control over your data

7. Children's privacy

Celestial Grimoire is not directed at children and we do not knowingly collect personal information from children. Because the app does not transmit personal data off-device in the first place, there is no server-side record of any user's data, child or otherwise, for us to hold.

8. Website purchase vs. Google Play

If you purchase Celestial Grimoire directly from our website, that transaction is handled by our website's own checkout system, which is separate from the app itself and covered by the website's own privacy policy and terms at the time of purchase. If you install Celestial Grimoire from Google Play, your purchase and payment information is handled by Google Play under Google's own privacy policy — we never receive your payment details in either case.

9. Changes to this policy

If we change what the app collects or how it behaves in a way that affects this policy, we will update this page and the "Effective date" above before that change ships. We will not retroactively reinterpret a past version of this policy to justify a practice that wasn't disclosed at the time.
