PRIVACY POLICY — MD READER
Effective date: October 31, 2026
App: MD Reader (com.tahatec.markdown)
Developer: Tahatec

SUMMARY
MD Reader opens, displays, edits and exports Markdown documents entirely on
your device. The app has no accounts, no sign-in and no servers of its own.
The documents you open or write are never uploaded and never shared with us
or anyone else. The network is used only for advertising, for the optional
push notifications, for the anonymous usage and crash reports described
below, and for web images inside a document if you choose to load them.
1. DOCUMENTS
- Files you open (from the file picker, "Open with" or "Share") are read
through Android's Storage Access Framework, which gives the app access to
that one file only. The app has no permission to browse your storage.
- When you press Save, the app writes back to the file you opened. Exports
(PDF, HTML, plain text, Markdown copies) are written only to the location
you choose in the system save dialog.
- Documents you create in the app ("My documents") are stored in the app's
private storage on your device.
- The app remembers the names and locations of recently opened files, and
where you stopped reading, so you can reopen them. This list stays on your
device; you can remove entries or clear it at any time.
- The clipboard is used only when you tap Copy.
2. WEB IMAGES AND LINKS
A Markdown document can contain images hosted on the internet. Loading such
an image tells its server your IP address and that the document was opened,
so web images are NOT loaded unless you tap to load them or turn on
"Load images from the web" in Settings. Links in a document open only after
you confirm the address, in the browser or app you choose.
3. INFORMATION THE APP STORES
Your preferences (theme, language, reading and editing settings, export
style, notification choice), the recent-files list, reading positions and
your own documents — all on your device only. Uninstalling the app deletes
everything it stored.
4. ADVERTISING
The app shows ads served by Google AdMob, which may also use certified
mediation partners such as Meta Audience Network. When requesting and
showing ads, these partners may collect and process data on their own
behalf, such as your advertising ID, IP address, coarse location derived
from it, and device and diagnostic information. This is standard for
ad-supported apps and is governed by the partners' own policies:
- Google:
https://policies.google.com/technologies/partner-sites
- Meta Audience Network:
https://www.facebook.com/about/privacy
Advertising partners never receive the contents or names of your documents.
In the European Economic Area, the United Kingdom and other regulated
regions, the app shows a consent form (Google's User Messaging Platform)
before any ad request is made, and you can change your choice at any time
under Settings → Ad privacy choices inside the app. You can also reset your
advertising ID or opt out of ad personalisation in your device's Google
settings.
5. USAGE ANALYTICS AND CRASH REPORTS
The app uses Google Firebase Analytics and Firebase Crashlytics to learn
which features are used (for example how a document was opened, or which
export format was chosen) and to receive reports when the app crashes. These
reports contain device and app information (model, OS version, app version, a
random installation identifier) but never a document's text, its file name,
its location, or the addresses of links in it. Firebase's handling of this
data is described at
https://firebase.google.com/support/privacy.
6. PUSH NOTIFICATIONS
If you allow notifications, the app registers with Firebase Cloud Messaging
so we can send occasional update announcements. Registration creates a
device token held by Google; it is not linked to your identity and we store
no list of recipients. You can turn notifications off at any time in your
device's app settings. The prompt is shown only after your first save or
export, never on launch.
7. PERMISSIONS AT A GLANCE
- Internet: advertising, consent form, analytics, notifications and, only
if you allow it, web images in documents.
- Notifications (Android 13 and later): requested only if you choose to
enable notifications.
- No storage, camera, microphone, contacts or location permission is used.
8. CHILDREN
The app is a utility, is not directed at children under 13, and we
knowingly collect no personal information from anyone, including children.
9. DATA DELETION
We hold no data about you, so there is nothing for us to delete: uninstalling
the app removes everything it stored on your device. Analytics and crash
data are held by Firebase under the policy linked in section 5, and
advertising data by the partners in section 4.
10. CHANGES TO THIS POLICY
If this policy changes, the updated version will be published at the same
address with a new effective date. Material changes will be reflected in the
app's store listing.
