Privacy Policy
Temporary addresses don’t have to mean unclear data practices. Here’s how TWININBOX collects, stores, and deletes information when you use temporary test email and email forwarding.
Email forwarding
Your login email is used for verification codes and forwarded messages. You can pause or delete each alias individually.
Limited retention
Forwarding records are kept for up to 30 days. Temporary addresses and messages follow the expiry time shown on the page.
You’re in control
Change your temporary address, delete stored messages, revoke aliases, or contact support to make a data request.
What information we process
When you use a temporary inbox, we process the assigned address, the sender, subject and content of messages, their arrival time, and session identifiers needed to show the expiry time. Don’t use a temporary inbox as the recovery address for a bank, medical service, or important account: anyone who knows the address or has the session information may be able to view its messages.
When you use email forwarding, we process the login email you provide, verification status, aliases you create, forwarding results, and security settings. Verification codes confirm ownership of your email address; we never ask for your email password. If you enable two-step verification, the setup key and verification status are used only to protect your account.
How and why we use information
We use this information to receive and display messages, deliver mail sent to your aliases to the email address you specify, troubleshoot delivery issues, and prevent abuse. We may also log limited request metadata, such as timestamps, error types, and network identifiers, to maintain security, prevent abuse, and diagnose faults.
We don’t sell message content or analyze inbox contents for advertising. If the law requires us to process specific data, we assess and respond to the request as applicable. We don’t promise absolute anonymity just because the service is temporary.
Retention and deletion timeline
| Data | Retention | Your options |
|---|---|---|
| Temporary addresses and messages | Until the expiry time shown in the inbox; 3 hours by default. You can extend it before it expires. | Changing your address invalidates the old one. Expired addresses and messages can’t be restored. |
| Forwarding records | Most recent 30 days | Delete them early from the dashboard |
| Forwarding aliases | Until you delete them or your account is terminated | Pause, reactivate, or delete them |
| Security and diagnostics logs | Kept for a limited time as needed for abuse prevention, operations, and legal requirements | Contact support to make a request |
Sharing and international transfers
Email delivery and basic hosting may involve email transmission and infrastructure providers. They process information only as needed to provide their services. Messages sent to your aliases are forwarded to your destination inbox, where the destination email provider’s privacy practices also apply.
Internet email travels across multiple networks and jurisdictions. Don’t use temporary addresses to send sensitive personal information, payment credentials, or anything you can’t risk exposing. We can’t control copies held by the sender’s or recipient’s systems.
Your rights and choices
You can change your temporary address on the page, or pause and delete aliases and forwarding records in the dashboard. You can also remove session information from your browser by clearing site data, but this may prevent you from accessing a temporary inbox that hasn’t expired yet.
To access, correct, or delete information associated with a long-term account, contact us from the email address linked to that account at support@twininbox.com. We may ask you to verify that you control the email address to prevent disclosure to someone who isn’t authorized.
Security and policy updates
We use measures such as access controls and encryption in transit, but no online service can guarantee zero risk. Keep your device, email account, and authenticator secure. Contact us promptly if you notice a suspicious login or misdirected email.
We may update this policy to reflect changes to the service or legal requirements, and will post the update date on this page. Where possible, we’ll notify you of significant changes in an appropriate way. Please review the current version before continuing to use the service.
