Read a policy before supplying data
Before filling in a form, identify the business requesting each detail and the stated purpose. Read its policy to see how it keeps information, with whom it may share it, and how it handles correction requests. A design resembling another page does not prove common ownership. A link may also pass through several domains; check where it ends.
To comment on an article at [email protected], a URL and description are usually enough. Do not send passwords, complete identity documents, or payment information. If an external service asks for such details in its own process, first confirm that you opened its official domain and understand why it asks.
If you have already given information to another company, use the channel it states for requests about that data. Keep a copy of the message and reply. This guide cannot change records held by third parties. Be cautious of an unexpected request with a very short deadline: urgency is not a replacement for verifying identity.
