Separate the interface from the service
A polished result grid can be a demonstration, a third-party API response or a live search. Look for explicit labels. Ask which provider supplies results and whether the trial searches the same index as the paid product. Facehunch’s fictional example and FaceCheck test mode are deliberately labelled separately.
Read the transaction details
Check what a credit buys, whether opening results costs extra, when subscriptions renew and where cancellation is handled. Record the terms presented at checkout. Do not infer a refund policy from a trial button or a competitor’s policy.
Evaluate claims with a controlled example
Use your own permissioned image with a known public source. Include an image you expect not to appear. Inspect whether returned pages support the result and whether the tool explains uncertainty. One successful search cannot establish a general accuracy rate.
Look for practical accountability
A clear operator identity, accessible privacy notice, removal process and support route are useful signals. Their presence is not a security audit. Avoid services promising access to private accounts or a complete personal history from a single image. Compare methods in the tool selection guide.
