This site sets no cookies and runs no analytics, advertising or tracking scripts. Its pages, styles and scripts come from the site itself. The site is hosted on GitHub Pages, which may keep ordinary server logs.

Documents
Certificates, letters, programme pages and lists are shown for viewing only. They open in an on-screen viewer; saving, dragging, copying and printing are switched off, and each image carries a faint watermark. Search engines are asked not to index these images. Private details are masked: dates of birth, parents’ names and registration, roll and serial numbers on the marksheets and the merit certificate, the signatures on the authorisation letters, and, on contact lists, other people’s names and every phone number.
No web page can fully stop a determined person from copying what appears on a screen. These steps stop casual saving and reuse; they are not a guarantee.
Verified copies, and contact details of the issuing organisations, are available on request by email.
Photographs
They show colleagues, students and community members at events and in classes. The faces of patients and survey respondents are blurred, and the names, faces and meeting code of online-class participants are hidden. Phone and payment numbers on posters are removed. Search engines are asked not to index the photographs.
If you appear in a photograph and would like it changed or removed, write by email and it will be dealt with promptly.
