Privacy Policy

Effective date: October 28, 2025

WhoPays ("we", "us", or "our") operates the WhoPays mobile applications (the "Service"). This policy explains what data we store, how it is used, and the choices you have.

Information We Store

Group data

  • Names you add for groups and members, expense notes, and balances are stored on secure cloud infrastructure so your group can stay in sync across devices.
  • Each user joins anonymously; we do not require email addresses or social profiles.

Usage diagnostics

  • We collect anonymized diagnostics (such as crash reports and basic feature usage) to improve stability. Diagnostics never include expense amounts, notes, or personally identifiable information.
  • Analytics and crash reports are provided by trusted platform services to help us spot issues quickly.

Exchange rates

  • Exchange rates are fetched from trusted third-party providers. The rates are cached briefly to ensure groups stay consistent. The data contains currency codes and rates only—no personal information.

How We Use Data

  • Sync groups in real time across iOS and Android.
  • Provide accurate balance calculations, including multi-currency conversions.
  • Diagnose crashes and measure anonymous feature adoption to guide improvements.

We never sell your data, and we do not run ads in WhoPays.

Data Control

  • Group owners can archive groups at any time, permanently removing the data from our servers.
  • You can delete the app to clear local caches. Cloud data remains available to other group members until the group is removed.
  • To remove all data associated with you, contact us and we will delete the underlying anonymous authentication record and any groups you own.

Security

  • We apply access controls that restrict group data to invited members only.
  • All traffic is encrypted in transit via HTTPS.
  • We review access logs and limit administrative access to the minimum required.

Children's Privacy

WhoPays is designed for adults managing shared spending. We do not knowingly collect personal data from children under 13. If you believe a child has provided data to us, contact us so we can remove it.

Changes To This Policy

We may update this Privacy Policy from time to time. Significant changes will be announced in the app or on this site, and the "effective date" above will be updated. Continued use of the Service after changes become effective constitutes acceptance of the revised policy.
