Who is responsible
C. Spencer is responsible for the personal information collected through this website. To ask a privacy question or exercise a privacy right, use the contact form and choose General question.
Ordinary website visits
The JotaTron website does not use advertising pixels or a newsletter signup. The webserver may create short-lived technical and security logs containing information such as request time, requested path, response status, browser details and network address. These logs are used to operate and protect the site and are not used to build marketing profiles.
Download register
Before the application ZIP or sample database is issued, you must supply a full name and email address. The server privately records those supplied details together with your requesting IP address, the selected file, a server-generated reference and the UTC date/time. The name and email are not identity-verified. A record means the server issued the file response; it cannot prove that your browser completed or retained the transfer.
This information is used to maintain a limited distribution record and protect the download service from abuse. It is not used for marketing, sold or shown publicly. The intended lawful basis is the owner's legitimate interests in managing software distribution and service security. You may object to this processing or choose not to request a download.
Contact messages
When you submit the contact form, the following information is stored on the JotaTron Ubuntu server:
- a server-generated reference and UTC date/time;
- the full name and email address you supply;
- your selected reason and free-text description;
- an internal New, Read, Closed or Spam status.
The information is used to read, manage and respond to your question or feedback, protect the form from abuse, and keep a reasonable record of the exchange. Your name and email are accepted as supplied; the site does not verify your identity. Contact messages are not added to a marketing list.
Anti-spam processing
The contact form uses Cloudflare Turnstile to distinguish legitimate submissions from automated abuse. The browser connects to Cloudflare when the challenge loads, and Cloudflare processes technical information for that purpose. Review Cloudflare's privacy policy for its processing. The server also applies rate limits and a hidden spam field. Full message text and email addresses are not intentionally placed in ordinary application logs.
Retention and deletion
Contact submissions and download-register entries are kept for up to 365 days unless they need to be retained longer for an active enquiry, security investigation or legal obligation. Automated retention removes older records from the live database. Private backups may retain deleted records until those backup copies expire.
Technical security logs should be retained only as long as needed for operation and abuse investigation. The exact webserver log rotation is managed on the hosting server.
Sharing and location
Contact records are stored privately on the JotaTron Ubuntu server and are not published. Information may be processed by infrastructure and anti-spam providers where needed to run and secure the service. It is not sold.
Your choices and rights
You may ask for access to, correction of or deletion of a contact or download record, or object to its continued use. Include the displayed reference if available. Some information may need to be retained where a legal or security reason applies. You may also raise a concern with the UK Information Commissioner's Office.
JotaTron desktop notebooks
This privacy page describes the website. The JotaTron desktop application keeps notebooks in local database files chosen by the user. It does not upload notebook content to this contact service. Do not paste passwords or private notebook contents into the website form.
