FAQ
What is a partner check?
A partner check is a photo-based search that scans public profiles on 50+ dating apps (Tinder, Bumble, Hinge, Ashley Madison, Feeld and others) to detect whether a specific person has an active or hidden dating profile. It uses facial recognition, takes under 60 seconds, and is completely passive from the subject's side — no like is sent, no profile is visited, no notification fires on their phone.
How does a partner check work?
You upload one clear photo of the person. The system extracts a facial signature (a mathematical representation of the face, not the image itself). That signature is compared against the public profile database of 50+ dating apps. If a match exists, you receive a report showing which apps, last-active timestamps, listed age and location, and screenshots. The whole process finishes in under 60 seconds.
How is a partner check different from a reverse image search?
A reverse image search (Google, TinEye) matches on the file — it looks for the exact same image republished somewhere on the open web. Dating apps do not publish their profiles to the open web, so reverse image search misses almost every hidden profile. A partner check indexes the dating apps themselves and matches on the face, not the file. Same face, different photo, still gets matched.
How is a partner check different from a background check?
A background check aggregates public records: criminal history, marriage records, sex offender registries. It has nothing to do with dating apps. A partner check searches only dating platforms. Someone can pass every background check and still have four active dating profiles.
How is a partner check different from hiring a private investigator?
A PI physically follows the subject, photographs meetings, and produces court-admissible evidence for a divorce filing. That costs $2,000 to $5,000 over two to four weeks. A partner check costs $19.99 and returns an answer in 60 seconds. Use a partner check to confirm suspicion; use a PI later if you need evidence a judge will accept.
Is a partner check legal?
Yes in the United States, Canada, the UK, the EU, Australia and most other jurisdictions. A partner check searches publicly accessible dating profiles, which is legally no different from browsing a public website. It does not access anyone's account, does not intercept messages, and does not install anything on any device.
Can the person being searched detect a partner check?
No. The search is performed against public profile databases, not against the subject's account. No like is sent, no profile visit is logged in their app, no notification appears on their phone. From their side of the screen, nothing happens at all.
How accurate is a partner check?
For a clear front-facing reference photo and unedited profile photos, match rates for active profiles are above 90%. Fake names, wrong ages and profiles set to different cities do not affect the result because the comparison happens on facial landmarks, not on text. Heavy filters on the profile photos or reference photos more than 10 years old are the main causes of missed matches.
How much does a partner check cost?
A single search on PartnerCheck is $19.99 and covers 50+ dating apps in one report. Lifetime monitoring, which re-runs the search on a schedule and alerts you if a new profile appears later, is available as an upgrade for $49.
Where does the term 'partner check' come from?
The term became common in 2024 and 2025 in Reddit relationship threads and TikTok, borrowed from 'background check' and shortened to describe a specific action: running one search to verify whether a specific partner has undisclosed dating profiles. By 2026 it had settled into common usage as the category name for photo-based dating app searches.
