FlexFinder by Snowhow — Altitude Management AS — Last updated: 18 October 2026
This policy covers the FlexFinder iPhone app, version 1.1 and later. It also covers version 1.0.4, the version before the new name, for as long as it is in use. Where the two differ, we say so.
The controller of your data is Altitude Management AS, Oslo, Norway. Contact: hello@snowhow.ski.
FlexFinder is a ski boot flex finder. While you ski, it uses your phone's GPS and motion sensors to measure how you ski, then works out the boot flex index that gives you the support you need. The calculation happens on your phone.
These are stored on your iPhone, in the app's own files:
Only what is listed under "What We Receive, and When" is ever sent to us. Your position, your route and the names are never sent. From version 1.1.2 the motion summary is sent from both Auto Mode and Manual Mode, as described below.
Starting a new session clears the measured runs and routes of the one before. "End session" clears them too. To delete a saved skier, press and hold the skier in "Who's skiing". Deleting the app deletes all of this. If you back up your iPhone, these files are included in that backup like other app data.
Version 1.1 asks once per phone, before anything is recorded: "Share your runs with Snowhow?" Sharing is off until someone answers "Share". The answer holds for everyone who skis with that phone.
You can change the answer at any time. Open the ··· menu on the session screen or the result screen, choose My profile, and switch "Share my runs" on or off. Switching off stops sending.
Manual Mode, versions 1.1 and 1.1.1. With sharing on, the app asks "How did this run feel?" after a run. If you tap Save, it sends us:
If you tap Cancel, nothing is sent. In these versions nothing else is sent: no coordinates, no route, no motion sensor data. Please do not put your name or other personal details in the note.
Auto Mode and Manual Mode, from version 1.1.2. The app no longer asks how a run felt. With sharing on, it sends when your flex number is ready, one record for each run of that session, whether you measured the run in Auto Mode or in Manual Mode:
Each run is sent once, at the moment the flex number is ready. If the phone has no signal at that moment, the run is not sent later. No rating and no note are sent from version 1.1.2. A run you measured while sharing was off is never sent later, also if you switch sharing on afterwards. Versions 1.1 and 1.1.1 send nothing from Auto Mode.
Share my result. The result card, and any photo you add to it, is made on your phone. It goes only where you choose to share it. We do not receive it.
With sharing off, nothing is sent. A rating or a run saved while sharing was off is not sent later.
Version 1.0.4 does not ask the sharing question. Each time you save a rating in Manual Mode, it sends the list above and the skiing level you chose when you set up the app.
Only to check and improve the flex model: to see how the flex index FlexFinder works out relates to how people ski and, in versions up to 1.1.1, to how they rated their boots. We do not use it for advertising, we do not build a profile of you, and it has no effect on the result the app shows you.
From version 1.1 the app sends data only after the answer "Share", so we rely on your consent (GDPR Article 6(1)(a)). You can take it back at any time in My profile. For version 1.0.4, which does not ask, we rely on our legitimate interest in checking and improving the flex model (GDPR Article 6(1)(f)). We keep the data limited: no name, no email, no coordinates. You can object at any time (see Your Rights).
FlexFinder asks iOS for location access "Always". iOS first lets you choose "Allow While Using App" or "Allow Once" instead. The reason we ask for more is Auto Mode:
Location is used on your phone to measure speed and altitude, to tell runs from lift rides, and (in Auto Mode) to keep the simplified route of each run. As described above, your position and route stay on your phone.
Motion access (accelerometer, gyroscope and barometer) is used while a run is being measured, and in version 1.1 to draw the live sensor lines on the waiting screen. The raw readings are reduced on your phone to a short summary. The raw readings are not stored and never sent. The summary is kept on your phone and, from version 1.1.2 with sharing on, sent as described above, from both Auto Mode and Manual Mode.
In Auto Mode the app also asks to show you a notification when your result is ready. The notification is created on your phone; we do not send it.
The data the app sends is received and stored by Netlify, Inc., the company that hosts snowhow.ski. Netlify is based in the USA, so the data is stored and processed outside Norway and the EEA. Contact us if you want details of how this transfer is safeguarded. Access to the stored data is restricted to us and protected by a secret access key; Netlify stores it on our behalf and must protect it to the same standard as this policy describes.
Like any web server, Netlify sees your phone's IP address when the data arrives. We do not store the IP address itself. To limit abuse, our server keeps a scrambled form of it for each record it receives. We use it only to protect the service against abuse.
We do not share your data with boot brands, retailers, advertisers or data brokers.
We have not yet set a fixed retention period. Until we do, we keep the data for as long as we need it to check the flex model, and you can ask us to delete yours at any time. When we set a fixed period, we will publish it on this page. The scrambled IP address is kept the same way. Data on your phone stays until you clear it or delete the app.
To stop sharing, switch off "Share my runs" in My profile. That stops sending from then on. To have what was already sent deleted, email us as described below.
Under the GDPR you can ask us to:
Email hello@snowhow.ski. Because we do not know who you are, we need a way to find your records. Tell us roughly when you skied with the app, your region, and the height and weight you entered. Any note you typed helps too. We will do our best to find them, and we reply within one month.
If you think we handle your data wrongly, you can complain to the Norwegian Data Protection Authority, Datatilsynet. We would appreciate the chance to put it right first.
snowhow.ski sets no cookies and runs no analytics or tracking scripts. Netlify, our host, processes your IP address to deliver the pages.
The homepage has an optional sign-up for release news. If you leave your email address there, it is stored by our email service, Kit, which is based in the USA, and we use it only to send the messages you asked for. We rely on your consent (GDPR Article 6(1)(a)), which you give by confirming the address. Every message has an unsubscribe link, and you can also email us to be removed.
We do not knowingly receive data from children under 13. If you are a parent and think your child has sent us data, email us and we will delete it.
If we change this policy, we will post the new version here and update the date at the top.
