Privacy
Last updated: 16 August 2026
This is a personal engineering blog run by Sahan Serasinghe in Adelaide, Australia. I collect as little data as practical, do not sell personal information, and do not use behavioural advertising.
Your choices at a glance
The site works when you choose essentials only. Optional features are separated so you can enable either, both, or neither:
- Remembered recommendations store topics and recently shown posts in this browser. This helps the featured section surface useful older articles.
- Analytics loads Google Analytics so I can understand which articles and site features are useful.
Neither optional feature runs before you choose it. You can change your choice at any time using Privacy settings in the footer. A browser-level Do Not Track setting also prevents Google Analytics from loading.
Information stored in your browser
| Storage | What it does and when it is used |
|---|---|
| Privacy choice | Remembers your settings after you make a choice. |
| Theme preference | Remembers light or dark mode when you change the theme. |
| Checklist progress | Saves the production readiness checklist on this device when you use it. |
| Recommendation history | Remembers reading topics and recently shown posts only when you enable remembered recommendations. |
| Google Analytics cookies | Distinguish visits during a browser session only when you enable analytics. |
These browser values stay on your device until you clear site data or change the relevant setting. Turning remembered recommendations off deletes their topic history. Turning analytics off asks Google Analytics to stop and removes its first-party analytics cookies from this site.
Services this site uses
Netlify hosting
Netlify serves the website. Like most hosting providers, it may process request information such as your IP address, browser details, requested URL, date and time for delivery, reliability and security.
Google Analytics
If you enable analytics, Google Analytics may receive the page URL, referring page, broad device and browser details, approximate region, engagement information, and events such as a featured-post click or newsletter form submission. I do not intentionally send your email address or article form contents to Analytics.
Analytics is configured to anonymise IP addresses, deny advertising storage and personalisation, and use session cookies rather than persistent analytics cookies. Google may process this information outside Australia. Google Analytics data is retained according to the retention setting on this site’s Analytics property.
EthicalAds
EthicalAds displays ads based on the page being read, not a behavioural profile. Its service receives ordinary web-request information needed to deliver, protect, and measure ads. EthicalAds says it does not use cookies or local storage for ad viewers and deletes identifying log data after 10 days.
Buttondown newsletter
If you subscribe, your email address and subscription activity are processed by Buttondown. This happens only when you submit a newsletter form. Every email includes an unsubscribe option. I keep subscription information until you unsubscribe, ask for deletion, or it is no longer needed to run the newsletter.
Algolia search
When you use the search page, Algolia receives the search query and ordinary request information required to return results. Search is not loaded on ordinary article pages.
These providers may process information in Australia, the United States, Europe, or other locations where they operate. Their linked policies explain their handling practices in more detail.
Contact and requests
You can ask what personal information I hold about you, request correction or deletion, or raise a privacy concern by emailing sahan.serasinghe@gmail.com. I may need enough information to identify the relevant record, such as the email address used for a newsletter subscription.
If this page changes materially, I will update the date above and ask for a fresh choice when the optional uses change.
