Privacy policy
Short version: most of our tools never see your files, we don't sell data, and we collect as little as we can.
Note for the site owner: this policy describes how the website is built. Have it reviewed by a legal professional for the countries you operate in before launch, and update it when you add analytics, advertising or new services.
Tools that run on your device
The Word Counter, Text Case Converter, Image Compressor, Image Resizer, Image Converter, PDF Merge & Split, QR Code Generator, Password Generator, Invoice Generator, Percentage Calculator and Unit Converter run entirely in your web browser. Your text, files and passwords are not uploaded to our servers.
The Invoice Generator can remember your business details in your browser's local storage on your device. You can clear them with the "Clear saved details" button.
AI tools
When you use an AI tool (AI Text Summarizer, AI Paraphrasing Tool, AI Email Writer, AI Social Caption Generator), the text you submit is sent securely to our AI provider, Google (Gemini API, paid tier), to produce the result. We do not store your text or the result. Under Google's paid API terms, your content is not used to train their models. To enforce the free daily limit, we keep a temporary, anonymized count linked to a one-way scrambled version of your IP address, which is deleted automatically within about 26 hours.
Please do not submit passwords, financial details or other sensitive personal information to AI tools.

Analytics and cookies
We may use privacy-friendly analytics to count visits and see which pages are useful. We do not use advertising cookies. If this changes, we will update this policy and ask for consent where the law requires it.
We remember your light or dark mode choice in your browser's local storage.
