Privacy you can verify
Every tool runs entirely inside your browser. Your data is never uploaded, stored, or shared — because it never leaves your device.
Your data is yours
We built every tool around one rule: process locally, store nothing.
Your files, text, and inputs are processed entirely inside your browser tab. Nothing is ever sent to our servers — because your data never leaves your device.
Every tool is pure client-side JavaScript. There is no server processing your input — you can open DevTools and watch zero data leave your browser while using any tool.
We don't create profiles, collect emails, or require any registration. You are completely anonymous to us — open a tool, use it, close the tab. That's it.
Browser-Based Processing
All 57 tools run 100% client-side. No file uploads. No API calls with your data. You can verify this yourself in your browser's Network tab — you'll see zero requests containing your tool inputs.
- Client-side JavaScript only
- Zero network requests with your data
- Verifiable in DevTools
Minimal Data Collection
We collect no names, emails, or personal data. Google Analytics tracks anonymised page views only, and you can opt out at any time via our cookie banner. Ad clicks are logged by Google, not us.
- Anonymous page analytics only
- Cookie opt-out available
- No email or PII collected
Ad-Supported, Not Data-Supported
We keep the lights on through Google AdSense display ads — not by selling your data. Your tool inputs are never shared with advertisers, analytics providers, or any third party.
- Google AdSense display ads only
- No data brokering or selling
- No behavioural profiling
How we protect your data
Privacy isn't a setting — it's the architecture.
All tool logic runs as JavaScript in your browser tab. Your data never touches our infrastructure.
There is no login system and no user database. No profile is ever created for you, anywhere.
All traffic to tools.twinkletara.com is encrypted in transit via TLS. No unencrypted connections.
Our cookie banner lets you accept or decline non-essential tracking. Essential functionality cookies only by default.
Ads are served by Google AdSense. Your tool inputs are never passed to any ad network or advertiser.
Every tool is client-side code. Open DevTools, check the Network tab, and see for yourself that no data leaves your browser.
