| Stripe | Payments (paid accounts only) | United States |
| Sentry | Error reports from the website and the app | United States |
| Google Firebase | Push notifications on your phone | United States |

Changes
Before a new company starts processing personal data, we add it to this page and email every account owner at least 15 days ahead. If we have to replace a company urgently for security reasons, we email you right after the change. If you object on data-protection grounds, write to privacy@mailmundo.com and we'll work it out with you; if we can't, you may close your account.
