Privacy Policy
Who we are
techedge.in ("we", "us", "this site") publishes articles on data engineering and applied AI, and offers a free email newsletter. This policy explains what data is collected when you visit or subscribe, and what choices you have.
What this site does not collect
Reading articles on this site does not require an account or any personal information. We don't track you across other websites, and we don't sell subscriber data to third parties.
What we collect when you subscribe
If you sign up for the newsletter, we store the following:
| Data | Why |
|---|---|
| Email address | To send you the newsletter |
| A hashed (not raw) version of your IP address | To prevent spam and abuse of the signup form |
| Browser user-agent string | Same — abuse prevention |
| Timestamp of signup | Record-keeping |
Your IP address is never stored in raw form — it's cryptographically hashed with a secret key before being written anywhere, so it can be used to rate-limit abuse but can't be reversed back into your actual address.
Cookies
The subscribe form uses a single, short-lived session cookie purely to protect the form against cross-site request forgery. It contains no tracking identifier and isn't used for analytics or advertising. See our Cookie Policy for details.
How your email is used
Your email is used solely to send the newsletter you signed up for. We don't share, rent, or sell subscriber lists. You can ask to be removed at any time by contacting us (see below).
Your rights
Depending on where you live, you may have rights to access, correct, delete, or restrict use of your personal data. To exercise these rights, contact us using the details below.
Children's privacy
This site is not directed at children under 13 (or the relevant minimum age in your jurisdiction), and we do not knowingly collect personal data from children.
Changes to this policy
We may update this policy from time to time. Material changes will be reflected in the "Last updated" date above.
