Privacy notice
What this website stores when you send a message or buy an app, why, and for how long, and what the StratumCode apps ask of it. Last updated 10 November 2026.
Who is responsible
This website is run by Theo van Stratum, trading as StratumCode, in Manila, Philippines. You can reach me through the contact form or at support@stratumcode.net.
What is collected
This site has no accounts, no tracking, no analytics and no advertising. It sets no cookies for visitors, and it loads nothing from other companies' servers.
The only personal information it stores is what you choose to send through the contact, enquiry and support forms, and what is recorded when you buy an app (described below). The forms store:
- your name and email address;
- your message;
- the topic, the app you chose and, on the support form, the app version and system version if you filled them in;
- the organisation, if you gave one on the enquiry form.
When you download an app from this site, it adds one to a counter for that app and that day, so that I can see which apps people use. The counter holds no address, no browser details and nothing that identifies you.
To limit spam, the site also keeps, with each message, a one-way scrambled version of your internet address (a salted hash, from which the address cannot be recovered) and the first 255 characters of your browser's identifying text. The scrambled address is used only to notice when one visitor sends many messages in a short time.
If you email me instead of using a form, your message and email address stay in my mailbox. I use them only to reply to you and to support you, I do not share them, and I delete them on request.
What the StratumCode apps send
The apps do not send your files, your name, your email address or your licence to this website or anywhere else. The one exception to staying offline is a request made about once a week by the versions downloaded from this website: it asks for a small public file, the list of withdrawn licences. The request contains nothing about you.
Like every request to a web server, it reaches this site's server together with the sender's internet address. This site does not use those requests to identify or track anyone. The versions sold through the Mac App Store make no such request.
When you buy an app
Payment is taken by PayPal, on PayPal's own pages. This website never sees your card details or your PayPal password. When you choose to buy, you are sent to paypal.com, and PayPal sends you back here when you finish or cancel. PayPal's own privacy statement applies to what you give PayPal.
For each purchase attempt this site stores:
- an order number, the app and the price;
- PayPal's references for the order and the payment, and the status (for example paid, cancelled or refunded);
- the date and time;
- once you have paid, the name and email address on your PayPal account;
- for 30 days, a one-way scrambled version of your internet address (a salted hash), used only to stop one visitor starting large numbers of checkouts.
This is used to confirm your payment, to make your licence and email it to you, to support you, and to keep accounting records. Licences are made by hand on the developer's own computer, and a licence contains your email address.
Why it is used
Only to read your message and reply to you, and, for a purchase, to confirm and support it as described above. Your details are not added to a mailing list, sold, or passed to anyone else.
How long it is kept
- The scrambled internet address is deleted after 30 days.
- A message and the details sent with it are deleted 24 months after it was last handled.
- Purchase records are kept for as long as is needed to support your licence and to keep proper accounts. The automatic clean-up that removes messages does not remove them.
- Either can be deleted sooner on request.
Your rights
You can ask to see what is stored about you, to have it corrected, or to have it deleted. Use the contact form or write to support@stratumcode.net, and say which message or order you mean, using the same email address. Records that the law requires me to keep cannot be deleted on request.
Where it is kept
Messages and purchase records are stored in a database on the server that runs this website, and are read only by me.
