This policy explains what cookies are, which ones Open Sigma Data Solutions Limited(“OpenSigma”) actually uses, and why. We keep this short because our use of cookies is deliberately narrow.
Cookies are small text files placed on your device when you visit a website. They can be used to remember who you are, keep you signed in, or track your behaviour across sites for advertising. We use them only for the first two.
We set only strictly-necessary cookies, required for the site to function:
Because these cookies are essential to providing the service you requested (staying logged in, submitting a form securely), consent is not required for them under the Uganda Data Protection and Privacy Act, 2019, or comparable regulations elsewhere.
Our website analytics run on Umami, a self-hosted, cookie-free analytics tool. It counts page views and referrers in aggregate without placing any cookie on your device or tracking you individually.
If you check out with PayPal, PayPal’s own site may set cookies once you leave our site for their payment flow. That is governed by PayPal’s own cookie and privacy policies, not ours.
Because we only set strictly-necessary cookies, blocking them will break sign-in and secure form submission. If you want to clear the session cookie, sign out of your account or clear your browser’s cookies for this site. Every modern browser also lets you block all cookies globally through its settings, though this will prevent you from logging in anywhere on the web, not just here.
If we ever introduce analytics or advertising cookies that require consent, we will update this page and add a proper consent choice before any such cookie is set — not after.
