Red Flag turns a public social media profile into a readable summary of what that account already shows to anyone who visits it. Enter a public username and Red Flag compiles a report from public information only: how many accounts the profile follows and is followed by, how often it posts, which accounts it has recently followed, and how those accounts group by content category. WHAT YOU GET • Activity index — a plain-language summary of a profile's public activity • Account types — how the accounts a profile follows group by category: creators, brands, artists, sports, gaming, lifestyle and more • Mutual connections — public follows that go in both directions • Profile stats — follower, following and post counts as the profile displays them • Weekly refresh — saved reports update once a week while you're subscribed FOR ENTERTAINMENT ONLY Red Flag reads only what a public account already displays. It cannot see private accounts, direct messages, or anything an account has not chosen to make public. It never logs in to, posts to, or interacts with any social network on your behalf. Every result is an AI-generated estimate of patterns in public activity. Results are not statements of fact about any person. Red Flag makes no claim about anyone's character, relationships, honesty or conduct. Red Flag is not a monitoring, investigation or background-check tool. Using it to harass, stalk or monitor another person is prohibited and may end your access. PRIVACY Your searches stay on your device. Usernames and display names shown in reports are partially masked. SUBSCRIPTION Red Flag offers weekly and annual subscriptions. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage or cancel your subscription in your Apple Account settings.
