Privacy
Privacy Policy
Effective July 28, 2026 · Electronic Supply International LLC
The short version: our software runs on your device, works offline, and does not collect, transmit, or sell your data. We don't run ads, analytics, or trackers. There is no account to create. What happens on your machine stays on your machine.
Our applications (Windows and Android)
Applications published by Electronic Supply International LLC — including the Tech Guru Suite tools and our Guru-chan apps and games — are designed to work entirely on your device:
- They do not collect, store, or transmit personal data.
- They contain no advertising, analytics, or tracking of any kind.
- They do not require an account and work offline.
- Files you open or create with our tools stay on your device and are processed locally.
- Where an app requests a device permission (for example, microphone access for the instrument tuner, or camera access for the flashlight's torch control), that permission is used solely for the app's stated function, on-device. Nothing is recorded or transmitted to us or anyone else.
Purchases
Purchases are processed by the storefront you buy from (Microsoft Store, Google Play, or others). We receive aggregate sales reporting from those platforms but never see your payment details. Their handling of your purchase is governed by their own privacy policies.
This website
electronicsupplyinternational.com is a static website. It sets no cookies, runs no analytics, and includes no third-party trackers. Your light/dark theme preference is stored in your own browser's local storage and is never transmitted. The site is hosted on GitHub Pages, which, like any web host, may record standard technical logs (such as IP addresses) as described in GitHub's privacy statement; we add nothing on top.
If you contact us at support@electronicsupplyinternational.com, we use your email address and message solely to respond to you. We don't add you to mailing lists, and we don't share your correspondence with anyone.
Children
Our software collects no data from anyone, including children. Our apps and games are suitable for general audiences unless a store listing states otherwise.
Changes
If a future product ever changes any of the above — for example, an online feature that genuinely requires data to function — we will update this policy before that product ships and state plainly what changed. The effective date above always reflects the current version.
