Our commitment
- ComTools online tools (JSON, Excel, images, etc.) run in your browser whenever possible — your data is not uploaded.
- We do not retain any data produced while using the tools.
- Feedback requires sign-in; messages are only used to improve tools and respond to requests, never commercially.
- We do not sell or share your personal information with third parties.
- Questions? Contact us via the feedback page.
How tool data is processed
JSON format/minify/validate and image OCR/compress run locally in your browser — content is not sent to our servers. Excel merge/split/SQL requires temporary upload; files are deleted immediately after processing. We do not backup, analyze, or retain your spreadsheet content.
Cookies and analytics
We use Google Analytics (gtag.js) to measure traffic and improve the site. Analytics may set cookies and collect anonymized visit data (page URL, duration, device type). You can block cookies in your browser or use Google's opt-out tools.
Third-party services
We may use Google Analytics (traffic stats) and Google Fonts (font delivery). Each service has its own privacy policy. Beyond these, we do not sell or share your tool data with third parties for commercial purposes.
Advertising disclosure
To keep services free, ComTools may display third-party ads (e.g. Google AdSense) in the future. Ad content is provided by third parties and may use cookies for personalization. We do not sell your tool usage data or file content to advertisers. This policy will be updated when ads are enabled.
Account and feedback data
When you register, we collect username, email, and display name for sign-in and public feedback. Passwords are stored encrypted. Feedback is publicly visible — do not include sensitive personal information.
Your rights
You may request access, correction, or deletion of your account data and opt out of non-essential cookies. Contact us via feedback to delete your account or messages. We will not use your personal information for marketing without consent.
Policy updates
We may update this policy from time to time. Material changes will be highlighted on the site. Continued use of ComTools means you accept the updated policy. Last updated: June 2026.
