Part 1 — Privacy Policy
Who we are
McMuse turns a photo you already have into a piece of art, in one of sixteen styles. The rendering is done by Google's Gemini image model; the artwork comes back to your phone and is kept there. It runs on Android.
McMuse is published by iDataGear Inc, a company incorporated in British Columbia, Canada. Where this policy says we or us, it means iDataGear Inc.
There is no account to create and no sign-up. McMuse does run one service of its own: it receives the photo you choose, has it rendered, and returns the artwork. It writes no photo and no artwork to any disk of ours. The only thing we keep is described under What we hold on our side below.
What the app keeps on your device
The app writes the following to private storage on your device — an area other apps cannot read. It stays there until you delete it or uninstall the app.
| What | Why | Where it is kept |
|---|---|---|
| Your artworks | The images the app made for you, as files, and the index that lists them. | Your device only |
| Tags and favourites | The words you attached to an artwork, and which ones you starred. | Your device only |
| Your AI processing choice | The date you agreed that a photo may be sent to be rendered, so you are not asked again every time. | Your device only |
| Settings | Language, theme, audio and display preferences. | Your device only |
None of this is uploaded to us. We cannot read it, cannot recover it for you, and are not able to hand it to anyone else, because it never reaches us.
What leaves your device
This is the complete list. Everything not named here stays on your device.
| What is sent | Who receives it | Purpose |
|---|---|---|
| The photo you choose, and the style you picked | iDataGear's McMuse service, then Google's Gemini API | To render the artwork and send it back. The photo is held only for the length of the request and is written to no disk of ours. Location and every other EXIF tag is removed before the photo leaves your device. |
| An anonymous installation identifier | Google Firebase Authentication and Firestore | To hold the credit balance for this installation. It is a random identifier, tied to no name, email address or device identifier. |
| A device attestation token | Google Play Integrity, through Firebase App Check | To show a request came from a genuine installation of this app rather than from a script. |
| Nothing automatic | Websites you tap | Opening a link in the app hands it to your browser, which then behaves as your browser does. |
What we hold on our side. One record per installation, under a random identifier the app is given when it first runs: the number of credits that installation has left, and whether its starter credits were granted. There is no name, no email address, no device identifier, and no history of what you made attached to it. It is kept until you ask us to remove it — write to idatagear@gmail.com with nothing more than a request to delete, and we will remove the record. Uninstalling the app does not remove it on its own, because nothing in the record identifies you well enough for us to find it without being told.
Separately from the list above, anything you deliberately send — through the system share sheet, an export, a printout or the clipboard — goes wherever you send it. That is your choice each time, and it is not covered by the table above.
What the app does not do
For as long as this policy is the current one:
- There is no sign-up, no email address, no password and no profile. The app signs in anonymously so that a credit balance can exist, and that identifier is all it is.
- We do not store your photo or your artwork on a server. The photo passes through to be rendered; the artwork comes straight back to your device.
- Your photos are not used to train any model of ours, and we do not ask Google to use them for training.
- We do not sell your personal information, and we do not share it for cross-context behavioural advertising.
- The app does not track you across other companies' apps or websites, and shows no App Tracking Transparency prompt.
- This version contains no analytics SDK and no crash-reporting SDK.
- The app does not ask for or read your location.
- The app does not record audio and requests no microphone access at runtime.
- The app does not read your contacts, calendar, messages, call log or files outside its own storage.
Permissions, and why each one is asked for
Each permission below is requested for one stated purpose and used for nothing else. On both platforms you can refuse or withdraw any of them in system settings; the features that depend on them stop working, and the rest of the app carries on.
| Permission | Platform | Purpose |
|---|---|---|
| Internet access | Android | Required for the network requests listed above. |
| Storage (older Android only) | Android | Saving files on Android 9 and earlier. Not requested on newer versions. |
| Camera | Android | Not requested. Taking a photo opens the system camera app, which owns the camera; McMuse receives only the picture you keep. |
| Photo library | Android | Not requested. Choosing a photo uses the Android photo picker, which hands over only the item you select. |
| Location | Android and iOS | Not requested. |
| Microphone | Android and iOS | Not requested. |
Analytics and crash reporting
This version of the app contains no analytics SDK and no crash-reporting SDK. We receive no usage statistics, no crash reports and no diagnostic data from it.
Subscriptions and purchases
We collect no payment information of any kind. Where an installation has credits, they were granted by our own service; the app never asks for card details and none reach us.
When you choose to share something
Sharing, exporting, printing and copying are always started by you. When you use one, the app hands the item to the destination you pick — another app, a contact, a folder, a printer — and what happens to it afterwards is governed by that destination, not by this policy.
Keeping and deleting your data
Everything the app keeps is on your device, so you control how long it lasts.
Delete an individual item inside the app to remove it. To remove everything at once, uninstall the app: the operating system deletes its private storage, and with it every item in the table above.
The record described above is kept for as long as the installation exists, because it is what makes your remaining credits remaining credits. Ask us at idatagear@gmail.com and we will delete it. Your photos are not part of it: they are never written down on our side, so there is nothing of them to keep or to delete.
Your rights
Under the GDPR, the UK GDPR, the CCPA as amended by the CPRA, Canada's PIPEDA and comparable laws elsewhere, you have rights over personal information held about you — to know what is held, to obtain a copy, to correct it, to have it deleted, and to object to or restrict its use.
For this app those rights are already satisfied by the design rather than by a request to us: the data is on your device, you can read it in the app, change it, export it and delete it, and we hold no copy to produce, correct or erase.
We do not sell personal information, and we do not share it for cross-context behavioural advertising as the CPRA defines those terms. There is accordingly no sale to opt out of.
If you believe we hold something about you regardless, write to idatagear@gmail.com and we will answer. You may also complain to your local data-protection authority.
International transfers
We are based in Canada. The third-party services named in this policy are operated by companies based in the United States and may process data in any country where they run infrastructure, under the transfer safeguards set out in their own policies — for Google, the European Commission's standard contractual clauses.
Children
This app is made for a general audience. It is not directed at children under 13, and we do not knowingly collect personal information from a child.
There is no account system, no messaging, no social feature and nothing another user can post or see — so there is no route by which a child using the app could disclose anything to us or to anyone else.
If you believe a child has given us personal information, write to idatagear@gmail.com and we will delete it.
Security
App data is held in the operating system's private per-app storage, protected by the device's own sandbox and by full-device encryption when a screen lock is set. Setting a passcode, PIN or biometric lock is the single most effective thing you can do to protect it.
Every network request the app makes uses HTTPS. No method of storage or transmission is perfect, and we cannot guarantee absolute security.
Changes to this policy
We update this policy when the app changes. The date at the top of the page is the date of the current version, and the change is published here as soon as it takes effect.
If a change means the app begins collecting something it did not collect before, we will say so plainly rather than leaving you to compare two versions of the text.
Part 2 — Terms of Use
1. Accepting these terms
By installing or using the app you accept these terms. If you do not accept them, do not use the app and remove it from your device.
These terms are between you and iDataGear Inc. Where you obtained the app from the App Store or Google Play, that store's own terms also apply to the transaction, and in case of conflict on a matter the store governs — payment, refund, redownload — the store's terms prevail.
2. Your licence to use the app
We grant you a personal, non-exclusive, non-transferable, revocable licence to use the app on devices you own or control, for your own use, in the ordinary way the platform intends. We keep all other rights.
You may not copy, sell, rent, sub-license or redistribute the app, reverse engineer or decompile it except to the extent that law expressly permits despite this clause, remove or alter any notice inside it, or use it to build a competing product.
3. Your content is yours
Anything you create in the app is yours. We claim no ownership of it and no licence over it. Because it stays on your device, we could not use it even if we wished to.
You are responsible for backing it up. Uninstalling the app, resetting the device, or losing or replacing the device removes what the app stored, and we hold no copy from which it could be restored. Export anything you would mind losing.
4. Acceptable use
Use the app lawfully. In particular, do not use it to break the law or anyone's rights, to record anyone where recording them requires their consent and you do not have it, to interfere with its operation or security, or to attempt to obtain fees, features or content you have not paid for.
5. Purchases, renewal and cancellation
Nothing in this section applies to the current version of the app. If that changes, this page will be updated before the change ships.
6. Accuracy of the content
The content in the app is provided for learning and reference. Language is disputed, regional and always moving, and dictionaries, translations, transliterations, pronunciation scores, stroke orders and recognised text can all be wrong. Do not rely on any of it where being wrong would matter — in an examination, a legal document, a medical setting or a contract — without checking it independently.
7. Third-party services
The app uses third-party services named in the privacy policy above. Each is governed by its own terms and privacy policy, we do not control them, and we are not responsible for what they do. Links out of the app to other websites are provided for convenience and are not an endorsement.
8. No warranty
The app is provided as is and as available, without warranty of any kind, express or implied, including any implied warranty of merchantability, fitness for a particular purpose, accuracy or non-infringement. We do not warrant that it will be uninterrupted, error-free, compatible with every device, or that defects will be corrected.
Some jurisdictions do not allow the exclusion of implied warranties, so parts of this clause may not apply to you, and nothing here limits a consumer right that cannot lawfully be limited.
9. Limitation of liability
To the fullest extent the law allows, we are not liable for indirect, incidental, special, consequential, exemplary or punitive damages, nor for lost profits, lost data, lost recordings, lost routes or lost progress, however caused and on any theory of liability, even if we were told such damage was possible.
Where liability cannot be excluded, our total liability for all claims arising out of the app is limited to the greater of the amount you paid us for it in the twelve months before the claim, or twenty Canadian dollars.
10. Changes and termination
We may change, suspend or discontinue the app, or any part of it, at any time. We may update these terms; when we do, the date at the top of this page changes, and continuing to use the app after that is acceptance of the updated terms.
This licence ends if you breach these terms, and it ends whenever you remove the app from your devices. The sections on your content, warranty, liability and governing law survive.
11. Governing law
These terms are governed by the laws of the Province of British Columbia, and the federal laws of Canada that apply there, without regard to conflict-of-law rules. The courts of British Columbia have exclusive jurisdiction over any dispute, and you and we submit to them — except that either of us may seek injunctive relief in any court with jurisdiction.
If a provision of these terms is held unenforceable, the rest stays in force. Nothing here removes a mandatory consumer protection of the country you live in.
