Mayer Money Privacy Policy
Last updated: November 10, 2026
Mayer Money is a private budgeting app run by Brad Mayer for his own household. It is not offered to the public. This policy explains what the app does with your information if you are a household member who uses it.
What we collect
- Bank information you choose to share. When you connect a bank through Plaid, Mayer Money receives the account names, types, balances and transactions for the accounts you select. You can also upload CSV files downloaded from your bank.
- Your sign-in. A user name and a scrambled (hashed) form of your password. We never store the password itself.
- Your edits. Budget changes, category fixes and notes, with your user name and the time.
Mayer Money never receives your bank password. When your bank uses its own sign-in page, you sign in there directly.
How we use it
Only to show the household its budget, spending, balances and savings. We don't sell, rent or share your information with anyone, use it for advertising, or use it to make credit decisions.
Who we share it with
- Plaid, which connects Mayer Money to your bank. Plaid's handling of your data is covered by the Plaid End User Privacy Policy: https://plaid.com/legal/#end-user-privacy-policy. You can see and manage the connections Plaid holds at https://my.plaid.com.
- No one else. The app runs on a computer in our home. Data is not stored with any other cloud service.
How we protect it
Every sign-in needs a password and a code from an authenticator app, and remote access only works from devices the owner has approved. Connections from outside the home are encrypted, bank connection keys are encrypted at rest, and only the owner's administrator accounts can reach the stored files. More in our Security Overview.
How long we keep it, and deleting it
We keep financial history while the app is in use, because spending history is what the app shows. Backups are kept for 30 days. The owner can disconnect a bank at any time; this ends the Plaid connection and deletes that bank's data from the app. To have all of your data deleted, ask the owner; it will be done within 30 days.
Changes
If this policy changes, household members will be told before the change takes effect.
