Local Sharpen

Images you open in Local Sharpen are decoded, sharpened and exported inside your browser. They are not sent to PhotoCrisper or any third party. You can confirm this in your browser's network tools, or by turning off your internet connection after the page has loaded.

AI Upscale

When you click Upscale, the image you selected is sent to our servers and forwarded to Kie.ai (operated by NEXUSAI SERVICES LLC, Denver, Colorado, United States), which runs the upscaling model. Your image is therefore processed in the United States. Before forwarding, we remove metadata such as EXIF and GPS location. The image is not sent anywhere until you click Upscale.

Retention

  • Our servers: the uploaded image is held in memory only for the duration of the request and is not written to our storage.
  • Input file at Kie.ai: uploaded through Kie.ai's file upload API under a random file name and deleted automatically by Kie.ai 24 hours after upload.
  • Result: the upscaled image is hosted by Kie.ai. You can download it through PhotoCrisper for 24 hours after it finishes; after that PhotoCrisper no longer serves it. Kie.ai's documentation says generated files are kept for 14 days. It does not say when they are permanently removed from its systems, so we do not promise a deletion date for the result.
  • Task records: we keep a record of each task (image dimensions, scale, status, credit used, time) to provide billing history and refunds. These records do not contain your image.

Training

We do not use your images to train AI models. Kie.ai's Terms of Use say that users keep ownership of uploaded content and grant Kie.ai a license to use it "solely for the purpose of operating and improving" its services. Neither those terms nor its Privacy Policy say whether uploaded content is used to train models. If that matters for an image, use Local Sharpen, which never uploads it.

Account data

If you create an account, we store your email address, name (if provided), sign-in records and credit history. Payments are handled by our payment provider; we do not store card numbers.

Analytics and cookies

We use cookies that are necessary for sign-in and preferences. To understand which tools people use and where they get stuck, we also use two analytics services:

  • Google Analytics 4 (Google LLC) records page views and basic interactions, together with technical details such as browser, device type and approximate location derived from your IP address. It never receives your image, its contents or its file name.
  • Microsoft Clarity (Microsoft Corporation) records how pages are used — clicks, scrolling and mouse movement — and can replay a session and build heatmaps. Text you type into forms is masked. Images you open are shown from a temporary in-browser address or from an address that only your signed-in account can open, so Clarity cannot retrieve them and your images are not captured.

Both services set cookies (for example _ga, _clck and _clsk) to recognize a returning browser, and receive your IP address and browser details.

Your choice. Visitors from the European Economic Area, the United Kingdom and Switzerland are asked before analytics cookies are used: until you accept, Google Analytics runs without cookies (Consent Mode) and Clarity receives a "not consented" signal. You can change your choice at any time with Cookie settings in the footer. Google and Microsoft process this data under their own privacy statements: Google and Microsoft. You can also opt out with the Google Analytics opt-out add-on, by blocking third-party scripts or cookies in your browser, or by using a content blocker. See the Cookie Policy for the full list.

Deleting your data

  • Local Sharpen: nothing to delete — we never received the image.
  • AI Upscale results expire automatically (see Retention).
  • To delete your account and credit history, use Settings → Delete account, or email support@photocrisper.com from the account's email address. Some records may be kept where required by law (for example, payment records), and backups are overwritten on a rolling basis.

Children

PhotoCrisper is not directed at children under 16. Please avoid uploading identifiable photos of children to any online service unless you need to.

Changes

We will update the date above when this policy changes.
