1. Who we are
Evolved Tech Stack ("we", "us", or "our") is a software development studio based in Gauteng, South Africa. You can reach us at szarathk@gmail.com.
2. Scope
This policy covers:
- Our marketing website located at evolvedtechstack.co.za.
- All current and future Android applications distributed via Google Play under the Evolved Tech Stack developer account (see the Our Apps section or our Google Play listing for the latest catalog).
3. Information we collect
We designed our website and applications to work without collecting personal information. Specifically:
- No sign-ups or accounts are required. Our apps operate entirely on-device and do not send your tasks or personal content to us.
- Some apps in our catalog display advertisements served by Google AdMob, which may collect device identifiers and usage data to serve relevant ads. See Section 8 for details.
- The website contact button opens your email client so you can voluntarily email us. The contents of that email remain in your control until you send it.
4. Device permissions
Our apps request only the permissions needed for their core functionality. Any information accessed through those permissions stays on your device and is not transmitted to us.
5. Location Data
Some apps in our catalog (including ToDo) may request access to your device's location to provide geofence-based reminders. Location data is stored locally on your device and is not transmitted to us or shared with any third parties. Location access is optional and can be managed through your device settings.
6. Children
Our apps are intended for users aged 18 and older. We do not knowingly collect information from children under the age of 18. If you believe a child has provided personal information through our services, please contact us immediately.
7. Data retention
Because we do not collect personal information, we do not store or retain any user data on our servers.
8. Third parties
Some of our apps use Google AdMob to display advertisements. AdMob may collect device identifiers (such as the Android Advertising ID) and usage data to serve personalized ads. You can review Google's privacy policy at https://policies.google.com/privacy. You can opt out of personalized ads through your device's Google account settings under Ads → Delete advertising ID.
We do not share any other data with third parties.
9. Security
Our website is served over HTTPS via GitHub Pages. Any email communication you initiate is handled by your chosen email provider. We encourage you to avoid sharing sensitive information via email.
10. Changes to this policy
We may update this policy to reflect new products or practices. When changes are made, we will post the updated version on this page with a new "Last Updated" date.
11. Contact
For privacy questions or requests, contact us at szarathk@gmail.com.
