Privacy Policy — PerkVault

Effective Date: April 8, 2026. Last Updated: April 8, 2026.
Information We Collect
Data you provide is stored locally on your device. All personal and financial information you enter into PerkVault is stored using Apple's SwiftData framework and is not transmitted to Stonham Studios because PerkVault has no server backend.
PerkVault uses Mixpanel to collect anonymous usage analytics so the app can be improved. Analytics can be disabled in settings and do not include personally identifiable information.
PerkVault may introduce advertising in the future. If that happens, this policy will be updated before advertising-related data practices are introduced.
- Credit and charge card names, networks, and annual fees
- Card benefit details, dollar values, and usage amounts
- Rewards balances and redemption goals
- Renewal dates and card-specific notes

- App settings and theme preferences

How We Use Information

Stonham Studios does not use your information for marketing or advertising targeting.
Data Sharing

- Anonymous Mixpanel analytics may be processed to understand app usage and improve performance.
- Apple processes subscriptions and App Store transactions through its own systems.
- Information may be disclosed if required to comply with a valid legal obligation.
Data Retention
All personal data remains on your device. Deleting the app removes all stored data.
