To help you clean metadata, Tails include [[<i>Metadata Cleaner</i>|doc/sensitive_documents/metadata]], a tool to remove metadata in a wide range of file formats.
Metadata has been used in the past to locate people from pictures they took. For an example, see <a href="https://www.npr.org/sections/thetwo-way/2012/12/04/166487197/betrayed-by-metadata-john-mcafee-admits-hes-really-in-guatemala">NPR: Betrayed by metadata, John McAfee admits he's really in Guatemala</a>.
For example, if you log into different accounts on the same website in a single Tails session, the website could determine that the accounts are used by the same person. This is because websites can tell when 2 accounts are using the same Tor circuit.
To prevent an adversary from linking your activities together while using Tails, restart Tails between different activities. For example, restart Tails between checking your work email and your whistleblowing email.
If you worry that the files in your [[Persistent Storage|doc/persistent_storage]] could be used to link your activities together, consider using a different Tails USB stick for each activity.For example, use one Tails USB stick for your activism work and another one for your journalism work.
