FlashStacks does not collect, store, or share any personal data. Everything stays on your device. That's it.
FlashStacks does not collect, store, or process any personal information. This includes:
We do not use analytics, advertising tools, or tracking technologies of any kind.
FlashStacks offers optional in-app purchases. All payments are processed securely by Apple via StoreKit. We do not receive or store any payment details such as credit card information.
All app data — your stacks, cards, and preferences — is stored locally on your device. We have no access to this data.
FlashStacks does not use any third-party analytics, advertising networks, or data collection services.
We do not sell, trade, rent, or share any personal data — because we don't collect any.
FlashStacks does not knowingly collect any personal information from children under 13.
We comply with applicable privacy regulations including GDPR (EU) and CCPA/CPRA (California, USA). Because no personal data is collected, most rights under these frameworks do not apply.
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated date.
