Effective 23 September 2026 · Digital Wallet is a MyDoller tool. This page explains how the wallet handles your cards and documents. Your MyDoller account itself (email, Gift Points, etc.) is covered by the MyDoller Privacy Policy.
In one sentence: your cards and IDs are encrypted on your phone and stored in your own Google Drive — as secure as your own Google Drive, plus encrypted. MyDoller never receives them, and we never store your CVV.
1. Who we are
Digital Wallet is operated by MyDoller (mydoller.com), Alberta, Canada. Contact: adigitalgrowthcanada@gmail.com.
2. What the wallet stores, and where
- Your cards and documents (the type you choose and the photos you take) are encrypted on your device with a 256-bit AES-GCM key before they are saved.
- The encrypted copies are saved in a hidden, app-only folder of your own Google Drive (Google calls it “appDataFolder”). It does not show in your normal Drive, cannot be shared by accident, and no other app can open it.
- The encryption key is created on your phone the first time you set up and is kept in that same hidden folder, so you can restore your wallet on a new phone by signing in with the same Google account.
- An encrypted copy is also kept on your phone so the wallet opens offline. Your 4-digit PIN unlocks this phone only.
3. What we never store
- Your CVV / security code. Bank cards are saved from a front photo only — the back, where the CVV is printed, is never captured. Older versions allowed typing a CVV; any such value is deleted automatically.
- Your cards, photos, card numbers or documents on any MyDoller server. MyDoller cannot see them, and neither can Google (they are encrypted).
- Your Google password, or any other file in your Google Drive.
4. What Digital Wallet shares with MyDoller
Only account-level information, never card content: that you use Digital Wallet, when, the app version, a random device ID, whether you joined through an invite link, and (after you save your first card) that the invite should be rewarded. Details are in the MyDoller Privacy Policy.
5. Google permissions we ask for, and why
drive.appdata — to keep your encrypted cards and key in the hidden app-only folder of your Drive.drive.file — lets the app manage only the files it created itself. It gives no access to any of your other Drive files.openid, email, profile — to know which Google account your wallet belongs to (so only that account can restore it or reset your PIN).
Digital Wallet’s use and transfer of information received from Google APIs to any other app will adhere to the
Google API Services User Data Policy, including the Limited Use requirements. Google user data is used only to provide the wallet’s storage and restore features to you. It is never sold, never used for advertising, never transferred to others (except as needed to provide the feature, for security, or to comply with law), and no person reads it.
6. How secure is it — honestly?
Your wallet is as secure as your own Google Drive, plus encrypted. A leaked or shared Drive link, a lost phone without your PIN, or a curious person at Google cannot read your cards. But anyone who fully takes over your Google account could restore your wallet — so please turn on Google’s 2-Step Verification. We do not describe Digital Wallet as a “zero-knowledge vault”, because the key lives in your Google account by design (that is what lets you recover everything just by signing in again).
7. Your controls
- Download my cards (Settings) — a copy of everything. Note: that file is not encrypted; keep it safe.
- Delete a card — removes it from your phone and your Drive.
- Delete everything (Settings) — erases all wallet data from your phone and from your Google Drive, permanently.
- Remove the app’s access to your Google account at any time at myaccount.google.com/permissions.
- Delete your MyDoller account from your MyDoller dashboard.
8. Retention
Your cards stay in your Drive until you delete them (or the whole wallet). We cannot recover them for you if you delete them or lose access to your Google account — only you hold them.
9. Children
Digital Wallet is not intended for children under 13 (or the higher minimum age where you live).
10. Changes
We will announce important changes in the app before they take effect. Digital Wallet is free today; if paid plans start later you will get at least 30 days’ notice first.
