Summary for parents

  1. What Mossly does: you (the parent) record a short sample of your own voice. We use it to create a private voice model that reads AI-written bedtime stories aloud. Your child only listens — they never sign in, type, or talk to the app.
  2. What we collect: your account email (from Apple or Google sign-in), your voice recording, your child's name + age (you enter these), and the stories Mossly generates for you.
  3. What we don't collect: no location, no photos, no contacts, no browsing data, no advertising IDs. No ads, no third-party analytics, no data selling.
  4. Your voice is sensitive: a voiceprint is biometric data. We send your recording to our voice provider (MiniMax) only to build your model, and we treat it as a special category of personal data under GDPR.
  5. Your rights: re-record your voice, delete any story, or delete your whole account at any time in Settings. Account deletion is immediate and permanent.
  6. Markets: Mossly is offered in Taiwan and the United States. This policy covers Taiwan PDPA, US (CCPA), and EU/UK GDPR for any overlapping users.

1. Who we are

Mossly ("we", "us", "Mossly") is the data controller responsible for processing your information under this policy. Mossly is a bedtime-story app: a parent records their own voice, and Mossly generates personalized stories read aloud in that cloned voice. Contact us at developer@totaunion88.com with any privacy question, data-rights request, or to report a concern.

Mossly is offered in Taiwan and the United States and is operated from Taiwan. For data-rights requests from users in the European Union or the United Kingdom (e.g. travellers who downloaded from the US store), please reach us at the email above; we will respond within 30 days.

2. Accounts

Mossly has a single kind of account: a parent account, created by an adult (18 or older). There is no child login. A "child profile" is simply a few fields (name, age, language) stored inside the parent account so stories can be personalized — the child never signs in, has no username, and cannot enter anything into the app.

AccountWho creates itWho controls the dataSign-in
ParentAn adult (18+)The parentSign in with Apple (iOS) or Google (Android)
Child profileThe parent, inside their accountThe parent, on behalf of the childNone — children never sign in

We do not offer email/password sign-in. Authentication is handled by Apple and Google; we never see your password for those providers.

3. What we collect

Everything we collect is required to run the service. Mossly has no advertising SDK, no third-party analytics SDK, and no marketing data platform.

3.4 What we never collect

4. How we use what we collect

For each piece of data above, the only thing we do with it is what's in the "Why" column. Specifically, we use your data to: create your voice model, generate and read stories, run your account, and manage your subscription. We do not:

5. Third-party processors (sub-processors)

Mossly relies on the following providers to run the service. They process your data on our instructions only, as our sub-processors — not for their own purposes.

ProcessorWhat they doWhat we send
MiniMax (international nodes — Singapore / United States) Voice cloning and text-to-speech (reading stories in your voice) Your voice recording (to build the model) and story scripts (to read aloud)
Google (Gemini API, United States) Writes the story script The story topic plus the child's name and age
Supabase Inc. (Asia Pacific — Singapore) Hosts the database, authentication, private storage buckets, and server functions Everything in § 3 is stored in Supabase's managed infrastructure
RevenueCat, Inc. (United States) Manages subscription state and entitlements Your account user ID and subscription / purchase events (no card data)
Apple / Google Sign-in and in-app purchase billing Authentication tokens; billing is handled entirely on their side

No advertising, analytics, or attribution companies have access to your data. We do not use Google Analytics, Firebase Analytics, Mixpanel, Amplitude, Segment, Crashlytics, or any similar service in v1.

6. How long we keep it

DataRetention
Voice recording (your sample)Stored privately until you re-record or delete your account.
Voice modelKept until you delete it (by re-recording) or delete your account. On account deletion we also instruct our voice provider to delete the model.
Child profile (name, age, language)Active until you delete it or delete your account.
Generated stories (script + audio)Active until you delete the story or delete your account.
Account + subscription recordActive until you delete the account.
Account deletionImmediate and permanent. When you delete your account, your database rows and stored files are erased right away, and we instruct our voice provider to delete your voice model. There is no grace period and the deletion cannot be undone.

7. Children

Mossly creates stories for children, but it is a tool used by the parent. The account holder is an adult; the child never interacts with the app — they only listen to a finished story. Because of this:

If you believe a child has provided us information directly, contact developer@totaunion88.com and we will delete it.

8. Your rights and controls

You can do all of these from inside the Mossly app:

RightHow
Re-record (replace) your voiceSettings → My Voice → re-record. This replaces the old model.
Delete a storyLibrary → swipe a story → Delete.
Delete your entire accountSettings → Delete account. Immediate and permanent; also deletes your voice model.
Access or correct your dataEmail developer@totaunion88.com. Response within 30 days.
Withdraw consentDelete the account (above).

9. Security

No system is 100% secure. If we discover a breach affecting your personal information, we will notify you and the relevant supervisory authority within 72 hours where required (e.g. GDPR Article 33, Taiwan PDPA).

10. International data transfers

Our infrastructure is in Asia Pacific (Singapore). Some processing happens elsewhere: voice cloning and text-to-speech run on MiniMax international nodes (Singapore / United States); story scripts are written by Google Gemini (United States); subscription state is managed by RevenueCat (United States). When data leaves Singapore for the EU/UK context, we rely on the European Commission's Standard Contractual Clauses (SCCs) or the UK International Data Transfer Addendum.

11. Changes to this policy

If we make material changes, we will update the "Last updated" date above and, for changes that affect how we handle your voice or your child's data, surface an in-app notice the next time you open the app.

12. Region-specific rights

12.1 European Union (GDPR)

If you live in the EU, you have the rights of access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction (Art. 18), portability (Art. 20), objection (Art. 21), and withdrawal of consent (Art. 7(3)). A voiceprint is a special category of personal data under Article 9; we process it only on the basis of your explicit consent, which you give before recording and can withdraw at any time by re-recording or deleting your account. You may lodge a complaint with your national supervisory authority. Legal bases under Art. 6: your consent (Art. 6(1)(a) + Art. 9(2)(a) for the voiceprint) and performance of our contract with you (Art. 6(1)(b)).

12.2 United Kingdom

Same rights as EU GDPR, exercised against Mossly, with complaints to the Information Commissioner's Office (ICO).

12.3 California (CCPA / CPRA)

Exercise these at developer@totaunion88.com. Response within 45 days.

12.4 Taiwan (Personal Data Protection Act, 個人資料保護法)

If you are in Taiwan, under the Personal Data Protection Act ("PDPA") you may, with respect to the personal data we hold about you: (1) inquire and request to review it; (2) request a copy; (3) request supplementation or correction; (4) request that we stop collecting, processing, or using it; and (5) request its deletion. We collect your data to provide the Mossly storytelling service and process it within the scope of that purpose. Because a voiceprint is sensitive personal data, we collect and use it only with your separate consent, given before you record. To exercise any PDPA right, contact developer@totaunion88.com; you may exercise these rights freely and we will not provide the service in a way that penalizes you for doing so, except where a right's exercise makes the core feature (storytelling in your voice) impossible.

13. Apple and Google platform disclosures

Mossly is distributed through Apple's App Store and Google's Play Store, and our data practices are disclosed in Apple's App Privacy and Google Play's Data Safety sections. Consistent with those: we do not track you across other apps or websites (no ATT tracking), we use no advertising SDKs, and we support in-app account and data deletion.
