Privacy policy

Last updated: November 5, 2026

This policy explains what the Sendski iPhone app, the web app at app.sendski.com and this website (together, "Sendski", "we", "us") collect, why, and the choices you have. The short version: we collect what the app needs to work, you decide what friends and crews see, we don't sell your data, and the ads we show are not personalized.

What we collect

• Account: your email address (to send sign-in codes), or the account details Apple or Google share when you sign in with them (an email address, which with Apple may be a private relay address, and sometimes a name). We give new accounts a placeholder name until you choose one.
• Profile: the name and photo you choose, your home mountain, whether you ski or snowboard, and your settings.
• Location: while you have a ski day recording, the app uses your phone's precise location, including in the background with the screen off, to record your runs and lift rides. When you open the map, it uses your location to show where you are. We don't collect location at other times. A ski day can only be started at a ski resort on the map.
• Ski days: the GPS track, runs, lifts, times, speeds, vertical and distance of the days you record or import (files you choose to import, such as GPX).
• Live location: only if you turn it on, your current position while a day is recording and you're at a ski resort on the map, so the friends you chose, or everyone in your crews, can see you on the map. Outside a resort it pauses (your day keeps recording, and the people who can see you are told it's paused). It stops when the day ends.
• What you post and do: reviews, ratings, photos, comments, planned days, runs you want to ski or love, map reports, friends, crews, invitations, and people you block or report.
• Error reports: when something breaks, the app can send a short anonymous report (what went wrong, the screen, the app version and device type). It carries no account, location or personal details, and you can turn it off in Profile › Privacy. We keep these for up to 90 days.
• Technical data: like any website or app, our hosting providers receive your IP address and device information when you connect, and keep standard logs for security and reliability.

How we use it

• To run Sendski: sign you in, record and show your ski days, draw maps, and show your friends and crews what you've chosen to share.
• To show reviews, plans and leaderboards to the people you've chosen (see "What others see").
• To keep Sendski safe: handle reports, enforce our terms, and prevent abuse.
• To fix problems and improve the app.
• To show ads that pay for Sendski (see "Ads").

We don't sell your personal data, and we don't use it to build advertising profiles.

What others see

You control most of this in the app under Profile › Privacy:

• Your ski days and stats, whether you're skiing right now, and your live location: separate switches for friends and for crewmates. Live location is off for new accounts until you turn it on; accounts made before November 5, 2026 keep the choice they had, and you can change it any time.
• Leaderboards: your name, photo and records appear on public boards only if you turn that on.
• Reviews are public. You can choose to show them as "A skier" to people who aren't your friends.
• Your name and photo are visible to people you're friends or in a crew with, and on what you post publicly.

People you block can't see your profile or what you post, and you won't see theirs.

Ads

Sendski shows ads from Google (AdMob in the iPhone app, AdSense on the web) and our own promotions. We ask Google for non-personalized ads only, and we don't share your location, ski days, crews or friends with Google. Google may still use device identifiers, cookies or similar technology to serve ads, limit how often you see the same ad, measure them and prevent fraud. See how Google uses information from sites or apps that use its services. Ads never appear on the map or while you're recording a ski day.

Who we share it with

We use these companies to run Sendski. They process data for us under their own privacy and security terms:

• Supabase: our database, sign-in and file storage (your account, profile, ski days, posts and photos).
• Vercel: hosts the web app and this website.
• Mapbox: draws the maps. Your device requests map images from Mapbox, which receives your IP address and the area you're viewing; the Mapbox software in the app may also send Mapbox anonymous usage and location data to improve its maps (Mapbox privacy policy).
• Google: ads (above), sending our sign-in emails, and Google sign-in if you use it.
• Apple: Sign in with Apple if you use it, and the App Store.

We may also share information if the law requires it, to protect someone's safety, or as part of a sale or merger ofSendski (the new owner would have to keep this policy's promises).

How long we keep it

We keep your account data until you delete it or your account. Deleting your account (Profile › Privacy › Delete account) removes your profile, ski days, GPS tracks, reviews, photos, comments, friends and crews from Sendski; backups are overwritten within about 30 days. Anonymous error reports are kept for up to 90 days. Reports about content may be kept longer if we need them to deal with abuse.

Your choices and rights

• Change what friends and crews see, leaderboards, review names and error reports in Profile › Privacy.
• Turn off location access in your phone's settings (the app then can't record ski days or show you on the map).
• Edit or delete what you've posted, and delete your account, in the app.
• Ask us for a copy of your data, to correct it, or to delete it by writing to staff@sendski.com. Depending on where you live (for example California, the EU or the UK), you may have further rights, including to object to some uses or to complain to a data protection authority. We'll answer within the time the law requires.

Children

Sendski is not meant for children under 13, and we don't knowingly collect their data. If you believe a child under 13 has an account, write to us and we'll delete it.

Security and where data is stored

Data is sent over encrypted connections and stored with access controls that limit each person to what they're allowed to see. Our providers may store and process data in the United States and other countries. No system is perfectly secure; if something goes wrong that affects your data, we'll tell you as the law requires.

Changes

We'll update this policy when Sendski changes how it uses data. For significant changes we'll tell you in the app or on this page and change the date above.
