A temporary inbox can help you keep short-lived messages separate from your main email address. That separation is useful, but it is not a promise of complete anonymity or a reason to trust every incoming message. Temp Mail Ace uses browser-held access information to protect inbox access; the email address itself is not the authorization credential.
An address identifies an inbox; it does not unlock it
Someone may know the address because you entered it into a service or shared it with a sender. Knowing the address alone is not sufficient to read its messages through Temp Mail Ace. Private access information is also required. Treat the browser profile that holds that information as part of your inbox access, especially on a shared computer.
Local history belongs to that browser
The free workspace keeps local history in the browser. It is not automatic cloud synchronization. A second device or another browser profile does not inherit the first browser's history and authorization. Clearing site storage can remove information needed to open an active inbox. Expiry is separate: even preserved access information does not keep an expired inbox alive. See how inbox expiry works.
Temporary email does not hide every connection
The service you contact may still receive information from your interaction with it, including information you type into a form. A temporary address does not change the rules of that service or guarantee that it cannot associate your activity with other information. Do not use a temporary inbox as a substitute for evaluating a site's privacy practices.
Read the destination before opening a link
A message can contain a verification link, a download or a request for account details. Check the sender and destination against the service you intended to use. Do not enter a password on an unfamiliar page merely because a message contains a recognizable logo. A highlighted verification code is extracted from the message; it is not a security endorsement of the sender.
Remote images can reveal an opening
The message viewer blocks remote images by default. If you choose to load them, your browser may contact the sender's image server, which can reveal that the message was opened and expose connection information. Decide whether the image is needed before enabling it. Images already attached to the message and images hosted by an external server are not the same thing.
Treat attachments as untrusted files
Limits on file size and safe message rendering do not mean that every attachment is harmless. Only download files you expected from a source you trust, and consider the consequences before opening them. The current service does not claim that every incoming attachment has passed malware scanning.
Choose a lasting mailbox for lasting relationships
Use a permanent address for account recovery, purchase records, work and other communication you may need later. A temporary inbox is intended for tasks that still make sense when the address expires. For setup and receive-only limits, read the temporary email guide.
Practical questions
Is my address a password?
No. The address identifies the inbox; separate private information authorizes access.
Does temporary email make a sender trustworthy?
No. Review the content, links and attachments independently.
Can I use the same inbox across devices automatically?
Do not assume cross-device access or cloud history is available in the current free browser-bound workflow.
