Mio Privacy Policy

Effective: 5 June 2026

Mio is an Android app for sharing pet care updates inside a household. This page explains what data Mio handles, how to delete your account and data, and how to contact the developer.

Who runs Mio

Mio is built and operated by Eren Ozata as an independent developer. For any questions about this policy or about your data, contact erenozataa@gmail.com.

What data Mio collects

Data you provide directly

• Display name — the name you choose during onboarding, shown to other members of your household.
• Pet details — names, species, photos, and any notes you add about your pets.
• Log entries — action timestamps (e.g. "Fed at 14:30"), optional text notes, optional photos attached to entries.
• Profile photo — optional avatar you upload for yourself.
• Google account email — required to create or join a household; used to keep your data recoverable across device changes. Not used for marketing.

Data Mio generates automatically

• Anonymous user identifier — a randomly-generated ID from Firebase Authentication used during onboarding (Welcome screen) so the app can run before you sign in with Google. Linked to your Google account the moment you create or join a household, so your data is recoverable across device changes. Created automatically on first launch; you don't see it.
• Push notification token — a Firebase Cloud Messaging token used only to deliver pet update notifications to other household members on your devices.
• App interaction events — anonymized events like "pet added", "paywall shown" (via Firebase Analytics) so we can understand product usage in aggregate.
• Crash reports — when the app crashes, a stack trace plus your device model, OS version, and approximate language/region (via Firebase Crashlytics). Used for debugging.

Data Mio does NOT collect

• Your location (Mio doesn't ask for or use location data)
• Your contacts, calendar, microphone, or files outside the app
• Advertising identifiers
• Browsing history or activity in other apps

How your data is used

• Within your household — pet details, logs, photos, and your display name are shown to other members of households you join. This is the entire point of the app.
• To deliver push notifications — when someone in your household logs an action, Mio sends a push to the other members so they don't double-feed the pet.
• To operate the service — Mio uses Firebase (Google Cloud) for storage, authentication, push delivery, and crash reporting.
• To improve the product — anonymous analytics help us understand which features get used and where users get stuck.

Who your data is shared with

• Other members of households you join. Joining a household is opt-in (you enter a 6-character code shared by the household creator). Strangers cannot see your data.
• Google (Firebase) as our data processor. Firebase services run on Google infrastructure in EU regions. See Firebase Privacy & Security.
• Nobody else. Mio does not sell your data, does not show ads, and does not share data with third-party advertisers or analytics services other than Firebase.

How long data is kept

• Your account and personal data — kept until you delete your account (see below).
• Logs in shared households — when you delete your account, log entries you wrote stay so other members keep their pet's history, but your name is replaced with "Former member" so they're no longer linked to you.
• Crash reports — kept for approximately 90 days, then automatically purged by Firebase Crashlytics.
• Analytics events — aggregated in Google Analytics for approximately 14 months, then automatically deleted.

How to delete your account and data

What gets deleted

• Your display name and profile photo
• Your authentication record (Firebase Auth user)
• Your push notification tokens
• Pets and their photos in households where you are the only member
• Your pending join requests, if any

What is retained, and why

• Log entries you wrote in shared households stay so the other members keep their pet's history. Your name is replaced with "Former member"; the entries are no longer linked to you.
• Pets and shared household data where there are still other members remain so they can keep using the app.
• Anonymous crash and analytics data already collected before deletion may persist in aggregated form for up to 14 months (Analytics) or 90 days (Crashlytics); these contain no personal information.

Children

Mio is not intended for children under 13. We don't knowingly collect personal data from anyone under 13. If you believe we have, contact us at erenozataa@gmail.com and we'll delete the data.

Your rights (GDPR / general)

If you're in the European Economic Area, the UK, or another region with similar data protection laws, you have the right to:

• Access the personal data we hold about you
• Correct inaccurate data
• Request deletion (see "How to delete" above)
• Object to or restrict certain processing
• Data portability — request a copy of your data in a machine-readable format
• Lodge a complaint with your local data protection authority

To exercise any of these rights, email erenozataa@gmail.com. We respond within 30 days.

Security

All data sent between your device and Mio's backend is encrypted in transit (HTTPS / TLS). Data is stored on Google Cloud infrastructure in EU regions. Access is restricted via Firebase security rules — only you and members of your households can read your data through the app. In addition, Mio's operator may access account data — including your name, email, Pro status, household membership, and profile/pet photos — through a secured, access-controlled administrative tool, solely to operate, support, secure, and maintain the service.

Changes to this policy

If we update this policy in a way that meaningfully affects how your data is used, we'll surface a notice inside the app the next time you open it. The effective date at the top of this page indicates the latest revision.
