Images and tool inputs
Selected images, target sizes and dimensions are processed in browser memory. This version does not upload them to Toolkatsu servers or maintain a server-side image library. Leaving or reloading the page discards the working state. Downloaded files remain on your device until you delete them.
Language preference
The site stores your selected language in localStorage under tn-language. It remains in that browser until you clear site data. There is no account database or payment processing.
Hosting and connection information
The website is hosted using ChatGPT Sites. Serving the page necessarily exposes connection information such as IP address, requested URL and browser headers to hosting infrastructure. Infrastructure logging and retention are controlled by the provider; Toolkatsu does not specify an independently verified retention period for those logs.
Emails you send
If you email us, your address and message, including any attachments you choose to send, reach the operator’s Gmail mailbox and are used to respond to and investigate the request. Contact us to request deletion. Do not include sensitive files.
Advertising, cookies and consent
Toolkatsu includes the Google AdSense tag and uses Google’s certified consent management platform. AdSense review is pending at this update; adding the tag does not guarantee that ads are displayed. The tag may contact Google and use cookies or similar identifiers even when no visible ad appears. No separate visitor analytics product is installed.
Google and other advertising vendors may use cookies and device identifiers to serve and measure ads, prevent fraud and, where permitted by your choices, personalize ads based on visits to this and other websites. Advertising requests may include your IP address, browser and device information, page URL and consent choices. Images selected in the converter are processed locally and are not submitted as ad content.
For visitors in the EEA, UK and Switzerland, the Google consent message provides consent, refusal and options controls. You can revisit your choice through the privacy and cookie settings link supplied by Google when the message is available. Provider lists and individual choices are available in that message. Availability depends on region and Google service activation.
See how Google uses information from partner sites, Google Privacy Policy and Google My Ad Center. You can manage personalized advertising there, or use industry opt-out tools for participating third parties. Google and its partners determine their own retention periods; these are not the same as the converter’s temporary image memory.
