Read each provider's own wording about what happens to an uploaded photo, then choose the smallest action that respects your comfort and permission: upload to one service with a specific question in mind, or stop if any stated use is unclear or unacceptable. Do not treat either statement as an independent privacy audit, and do not upload a photo you lack permission to use.

Start with permission and a single question
Before comparing providers, confirm that you are the owner of the photo or have clear consent from anyone visible in it. A dating photo is often voluntarily shared by its owner, but that does not automatically permit reverse-image searching by someone else. Write one bounded question, such as whether a public-facing profile photo appears on pages you can already view. If the photo is intimate, shows identity documents or readable screens, or includes people who have not agreed, stop rather than searching for a provider whose wording feels more lenient.
- Write down who is in the photo and whether you have their consent.
- State your one question before opening any provider page.
What Microsoft says about uploaded image processing
Microsoft's Bing Visual Search support page describes accepting image-based inputs and returning related images, pages that use the image, and other information. The same page states that uploaded photos may be used to improve image-processing services, and it cautions that AI-generated visual results can contain mistakes. That is a vendor statement about service improvement, not a commitment that your image will never be retained or reviewed. Read it as a reason to ask whether the possible improvement use matters to you, especially for a photo that shows your face or a private setting. [Microsoft Support: Bing Visual Search]
What TinEye says about uploaded images and its index
TinEye's help article says uploaded search images are analyzed server-side and are not added to its web-image index. That addresses one specific question: whether your upload becomes part of the searchable index. It does not follow that the image is never stored, never reviewed, or handled in a way an independent auditor has verified. Treat the statement as a vendor description of that workflow, not as an independent security audit and not as a promise that applies to any other provider. [TinEye Help: uploaded image handling]
- Do not convert 'not added to the index' into 'never retained'.
- Keep the provider's exact wording available while you decide.
Compare the two statements side by side
The useful comparison is not which company sounds safer in general, but which stated use you can accept for this particular photo and question. Microsoft's page raises a possible service-improvement use; TinEye's page addresses index inclusion. Neither statement answers every question about retention, access, or deletion. Use the table below to separate what each page actually says from what you would be assuming, then choose a bounded upload or stop.
| observation | limit | next step |
|---|---|---|
| Microsoft says uploaded photos may improve image-processing services. | This is a stated possibility, not a full retention or deletion policy. | Decide whether that possible use is acceptable for this photo. |
| TinEye says uploaded images are analyzed server-side and not added to its web-image index. | This is a vendor statement about one workflow, not an independent audit. | Do not treat it as proof of how other providers handle uploads. |
| Microsoft cautions that AI visual results can contain mistakes. | A returned match is not proof of identity or current activity. | Use findings to judge the provider's stated use, not to confirm a person. |
Choose a bounded upload or stop without claiming an audit
If the stated use is acceptable and your question is narrow, upload one photo to one provider and look only for the public pages you already expected to find. If any stated use is unclear, if the photo includes someone who has not agreed, or if you would need to assume facts the provider did not state, record the control as unavailable and stop at the access boundary. Do not describe your decision as a privacy audit, a security test, or a guarantee. If you need current details, use the provider's official help page or ask the photo's owner for a voluntary current link rather than working around an unavailable control.
- Choose one provider and one photo, or stop.
- Write 'unavailable' if a documented control or permitted artifact is missing.
- Do not frame the result as an independent privacy audit.
A couple more questions
Does TinEye's statement mean my uploaded photo is never stored?
No. TinEye says uploaded search images are analyzed server-side and are not added to its web-image index. That is a vendor statement about one workflow, not a promise about all retention or an independent security audit.
Can I treat Microsoft's image-processing statement as a privacy guarantee?
No. Microsoft states that uploaded photos may be used to improve image-processing services and that AI results can contain mistakes. That is a stated possible use, not a guarantee about retention, deletion, or identity verification.
What should I do if I cannot confirm permission for the photo?
Stop. Do not upload a photo of someone who has not agreed. If you are the owner, you can still decide to stop rather than search, and you can ask the owner for a voluntary current link instead of working around an unavailable control.
