Privacy Policy
Prompt Optimizer Chrome extension. Last updated: November 6, 2026.
- When you run Optimize, your text is sent to our server and an AI provider to rewrite it.
- We don't store your text on our servers and keep no history of it.
- We don't sell your data, show ads or use analytics.
Who is responsible
Prompt Optimizer is run by its developer. For questions about your data, use the developer email on the extension's Chrome Web Store page. By using the extension, you agree to this policy.
What we handle
- Your text and the chosen format. Sent only when you run Optimize, click Try again or switch the format, so that it can be rewritten. Not stored on our servers.
- Install ID. A random identifier created when you install the extension. It contains no name or email. It is sent with each request to apply the free daily limit. It stays in your browser until you uninstall the extension; on our server it is kept with a request counter for up to 2 days.
- IP address. Used on each request to protect the free service from abuse. We keep it only as a hash combined with the date, with a request counter, for up to 2 days. A hash like this is not anonymous.
- Extension version. Sent with each request. Not stored.
- Format chosen in the side panel. Stays in your browser and is never sent on its own.
Our server keeps technical logs for 3 days. They contain no text, install IDs or IP addresses, only refusal codes, failure reasons, the model's name and token counts.
The extension doesn't read your conversations or the AI's replies, doesn't send anything while you type and doesn't track the sites you visit.
Who receives your text
- Cloudflare hosts our server.
- OpenRouter forwards the request to an AI model.
- The companies that host the model, such as Anthropic or OpenAI, generate the result.
Which provider handles a request depends on availability and cost, and it can change. We update this list when we add a provider.
These companies handle your text under their own terms. Depending on those terms and the model used, they may keep it for some time, and some may use it to improve their models. We don't control this, so please don't put passwords or other sensitive information in your text.
Our server and these companies may process your data outside your country, including in the United States.
Deleting your data
We keep no names, emails or text, so the only data we hold is the counters, which are gone within 2 days. Uninstalling the extension removes the data stored in your browser. We can't delete copies kept by AI providers; their own terms apply.
Chrome Web Store
We use your data only for the extension's single purpose, rewriting your text. We don't sell it or use it for advertising or for creditworthiness or lending decisions. The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
Changes
When this policy changes, we update this page and its date. If a change affects how your data is handled, we will also say so in the extension.
