Privacy Policy
Last updated: February 21, 2026
Overview
At Free Smart Tools Hub, we believe privacy is a fundamental right. Our Service is designed with a privacy-first architecture — all calculations, conversions, and image processing happen entirely within your web browser.
We do not collect, store, transmit, or sell any personal data. Period.
This Privacy Policy explains what data (if any) is stored locally, how third-party services may interact with your data, and your rights as a user.
Data Collection
Here's a clear breakdown of what we do and don't collect:
| Data Type | Collected? | Details |
|---|---|---|
| Personal information (name, email) | ✕ No | Never collected |
| Calculator inputs & results | ✕ No | Processed locally, never transmitted |
| Images uploaded for conversion | ✕ No | Processed in your browser only |
| IP address | ✕ No | Not logged by our Service |
| Theme preference | ✓ Locally | Stored in your browser's localStorage |
| Recently used tools | ✓ Locally | Stored in your browser's localStorage |
Local Storage
Free Smart Tools Hub uses your browser's localStorage to save a minimal set of preferences for a better user experience:
- Theme preference (light/dark mode) — so your preferred theme persists across visits
- Recently used tools — so you can quickly access your favorite calculators
This data is stored only on your device and is never transmitted to any server. You can clear this data at any time through your browser's settings (Clear Site Data).
No cookies, session tokens, or tracking identifiers are used.
Image Processing
Our Image Tools (WebP converter, AVIF converter, Image Optimizer, Image Resizer, etc.) process all images 100% locally in your browser using the HTML5 Canvas API.
- Images are never uploaded to any server
- Images are never stored beyond the current browser session
- Processing happens using your device's resources (CPU/GPU)
- Converted/optimized images exist only in your browser's memory until you download them
- Once you close the tab, all image data is automatically cleared from memory
This means your images remain completely private. Even we have no way to see or access them.
Third-Party Services
Free Smart Tools Hub uses the following third-party services:
- Google Fonts (fonts.googleapis.com) — to load the Inter typeface. Google may collect anonymized usage data as per their privacy policy.
We do not use:
- Google Analytics or any analytics services
- Advertising networks or ad trackers
- Social media tracking pixels
- Any server-side data processing
Cookies
Free Smart Tools Hub does not use cookies of any kind — no first-party cookies, no third-party cookies, no tracking cookies.
We use localStorage instead (which is not a cookie and cannot be used for cross-site tracking) to store your theme preference and recently used tools.
Children's Privacy
Free Smart Tools Hub is a general-purpose educational tool suitable for users of all ages. Since we do not collect any personal information from anyone, there are no special concerns regarding children's data.
Parents and guardians can feel confident that their children's privacy is protected when using our Service.
Your Rights
Since we don't collect personal data, traditional data rights (access, correction, deletion) don't apply in the usual sense. However, you have the right to:
- Clear local data — Delete your localStorage data through your browser's settings at any time
- Block third-party requests — Use browser extensions to block Google Fonts requests if desired
- Use offline — After the first load, most features work without an internet connection
- Contact us — Ask any questions about our privacy practices
Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Last updated" date at the top of this page.
