Privacy, by processing mode
Light
Light mode never leaves your browser.
Character operations, positions, visualization and diff are computed locally. Drafts and reports live in page memory and are discarded when you refresh or close it. The tool does not use localStorage or sessionStorage.
Standard and Deep
Standard and Deep rewrite your wording and are processed on our servers. The server algorithm uses a third-party processing service. This application does not save request text, response text, or text-bearing logs. We cannot promise that processing or hosting providers have no retention; review their policies before sending sensitive text.
The working draft stays in the page so you can retry a failed run. The server code does not write input or output to a database, file, analytics event, cache, or application log. Network providers and DeepSeek operate under their own policies; this is not a promise about their retention or training practices. These modes remain gated until deployment and provider review are complete.
Controlled bench experiments
Submitting a prompt on the verification page is a separate, explicit server action. We generate a new sample with our own SynthID-Text keys. The original words are not retroactively watermarked. Bench generation and embedding inference run on the configured bench server; an edited sample is sent to DeepSeek in Standard or Deep. We do not offer an endpoint that classifies arbitrary text as AI-generated.
Clipboard and analytics
Copy writes the result to your device's clipboard; operating systems and extensions may retain it. Optional analytics records only numeric metrics, booleans, and allowlisted mode/error enums. Text, tokens, characters, URLs inside drafts and provider payloads are excluded.
Infrastructure and contact
Ordinary page requests and provider operations may generate infrastructure metadata. Synthetic development fixtures are explicitly labeled, contain no submitted visitor text, and may be saved as reproducibility artifacts.
