Privacy policy.

Your calendar never leaves your PC. Here is exactly what we see, and why.

This policy covers the Desk/Laptop Calendar app for Windows and this website, delacalender.com. They are made by blackie-networks. Contact: support@delacalender.com.

What stays on your PC

Your calendar – appointments, reminders, tasks, calendars, holidays you choose and your settings – is stored only on your PC, in the app's own folder. We can't see it. It isn't uploaded anywhere. Daily backups are kept in the same folder. The app's log files record what the app does (for example “reminder scheduler started”), never the content of your items, and also stay on your PC unless you choose to send them to us.

What the app sends, and why

  • Licence check (website keys only). When you activate a licence key, the app sends the key and an anonymous device code to our licence server. The device code is a one-way scramble of your PC's ID; it can't be traced back to you or your PC. The app re-checks the key now and then so it keeps working. This is how we limit a key to 3 PCs.
  • Microsoft Store purchases. If you subscribe through the Store, Microsoft handles the payment under its own privacy statement; we only learn that a subscription is active.
  • Nothing else. No advertising, no tracking, no analytics, no account and no sign-in.

When you buy on this website

  • Payment is handled by Paystack (M-Pesa or card). We receive your email address, the amount and a payment reference – not your card details or M-Pesa PIN. See Paystack's privacy policy.
  • Your licence key is emailed to you through Brevo, our email service.
  • We keep the email, the key, its expiry and the payment record while the licence is active and for five years after, for accounting and tax, then delete them.

When you visit this website

  • No cookies, no trackers. We don't use advertising or analytics services. We count how many times each page is opened per day, and how many times the Microsoft Store button is clicked. Only these daily totals are stored – not your IP address, device or browser.
  • Messages you send us through the contact forms (your name, email and message) are used only to reply to you and are deleted within two years, or sooner if you ask.
  • Our servers keep short technical logs for security, which can include IP addresses, for up to 30 days.

Your rights

You can ask us to see, correct or delete the personal data we hold about you (your email, licence records and messages) at support@delacalender.com. Deleting your licence record ends the licence. You can also complain to the Office of the Data Protection Commissioner (Kenya).

Children

The app and this website are not directed at children and we don't knowingly collect data from them.

Changes

If this policy changes, we'll update the date above and note the change in the app's “What's new”.
