When reporting a bug
- Please include the device and browser you used, the step where the error occurred, and the error message shown on screen.
- Do not attach files containing personal data, such as the full ZIP, username lists, raw DMs, or advertiser lists.
- If the file structure needs to be checked, send an example showing only folder names and JSON keys, with values redacted.
- For content corrections, including the URL in question and supporting evidence speeds up the review.
Response standard
We aim to send a first reply within 2 to 3 business days. This is a response target, not a historical average response time. It may take longer if the issue is hard to reproduce or requires checking the Instagram export format.
Privacy and security inquiries
Please put "Privacy inquiry" or "Security report" in the subject line. Privacy inquiries are received at the email address above. Because CheckMate does not store uploaded files or result lists on a server, requests to delete that data from a server do not normally arise.
