Can I climb today
Who runs it
Can I Climb Today is made by Blok Sessions, the trade name of Frank Blokdijk (KvK 42113691), the Netherlands. Questions about your data go to hello@bloksessions.com.
This website
The site sets no cookies and runs no analytics. The forecast comes from Open-Meteo through our own server, so Open-Meteo never sees your IP address. Our host, Cloudflare, keeps short-lived request logs to run the site.
Near me works out distances in your browser and never sends your location.
The dry-rock emails
If you ask to be emailed when an area is dry, we keep your email address, the area, and when you signed up and confirmed. We use them only to send a confirmation email and then an email the evening before that area turns dry after rain, at most once every three days.
If you sign up for "Dry this weekend, near you", we also keep where you drive from, rounded to about 10 km, how many hours you'd drive and your language, and send one email on Friday mornings with the areas within that drive that look dry. Signing up in the iPhone app is the same email: the app sends your address, your drive and where you are, rounded to about 10 km.
Every email has a link that stops them straight away. We delete an address that's never confirmed after 7 days, and one that's stopped 30 days after you stop it. The emails are sent through Resend.
Blok Sessions' strength block
Next to the Friday email there's a box, unticked, for Blok Sessions' free strength block. Only if you tick it does your address also go to Blok Sessions' own email list, which sends its own confirmation email and the block's emails. That list is run under the Blok Sessions privacy policy, and every email on it has its own stop link.
The iPhone app
The app has no account. It asks for your location while you use it and uses it on your phone to find the areas nearest you; it isn't sent to us. To show the forecast it asks our server for the areas you saved, in your phone's language, and we don't keep those requests.
If you switch on "Tell me when it's dry" for an area, we keep your phone's push token, that area and your language. If you switch on "Dry this weekend, near you", we also keep where you drive from, rounded to about 10 km, and how many hours you'd drive. We use them only to send those notifications, through Apple's push service, and delete them when you switch the alert off or when Apple tells us the app is gone.
Tips are bought through the App Store. Apple handles the payment and we never see your payment details.
Rock reports
On an area's page, on the site and in the app, you can say whether the rock was dry, damp or wet today. We keep the area, what you said, what we had forecast for it, the language and the time, and nothing that identifies you: no account, no location, no device ID. We use them to check and improve the drying model, and the last 24 hours' totals show on the area's page.
Where it's kept
Email and notification sign-ups are kept in a database run by Supabase in the EU (Ireland). We don't sell any of it or share it for advertising, and we use it only for what's described here.
Your rights
You can ask what we hold about you, ask us to correct or delete it, or object to how we use it, by writing to hello@bloksessions.com. You can also complain to the Dutch data protection authority, the Autoriteit Persoonsgegevens.
