Privacy Policy

Privacy Policy
Effective 2026-08-30
Draft. This document is awaiting legal review and the operator details have not been filled in yet. Do not publish it in this state.
In short
Powe records your ski and snowboard days and, if you choose, shows your live position to friends you have added to a group.
Your recorded days stay on your phone unless you turn sharing on. Location sharing is off by default, is limited to groups you pick, and expires automatically at the end of the ski day.
We do not sell your data, we do not use it for advertising, and there is no third-party analytics or tracking in the app.
This document is published in English, and the English version is the one that applies. A translation will follow once it has been reviewed.
1. Who we are
Powe ("we", "us") is operated by TODO_BEFORE_LAUNCH, which is the data controller for the personal data described in this policy. You can reach us at TODO_BEFORE_LAUNCH or by post at TODO_BEFORE_LAUNCH.
This policy explains what we collect, why, who can see it, how long we keep it and what you can ask us to do about it. It covers the Powe mobile apps and the Powe website.
2. What we collect, and why
We collect only what a feature needs. Notably, we do not ask for your real name, date of birth or gender, because nothing in the app uses them.
Account and identity. When you sign in with Google we receive an account identifier, your name, your profile picture and your email address. We request only the OpenID Connect scopes "openid", "email" and "profile" and nothing further. We use the account identifier to recognise you across sign-ins, and your name and picture so your friends can identify you. We use your email address to contact you about your account. If you sign in with Apple and choose Hide My Email, we receive a relay address and store it as such.
Profile you give us. A display name, an optional unique username so friends can find you by searching, an optional photo, whether you ski or snowboard, your self-described ability, an optional home resort, your unit preference, your sharing preferences, which powmates and which groups you have starred as favorites, and an optional emergency contact name and phone number. Ability is used so group features do not suggest terrain beyond it. Your favorite powmates and favorite groups are stored so the lists order them first for you, are never shown to anyone else, and are cleared when you delete your account. The emergency contact is stored only if you enter one, is never shown to your groups, and is not shared with anyone automatically.
Location and motion, while you are recording. Latitude and longitude, GPS altitude and its reported accuracy, speed, and barometric pressure from your device's sensor. Pressure is what makes vertical descent accurate, because GPS altitude alone carries ten to twenty metres of error. We use these to detect your runs and lift rides and to calculate your statistics. Recording only happens while a session is active, which you start and stop.
Presence, only while you are sharing. When you turn sharing on we send your position and altitude, what you appear to be doing (descending, riding a lift, climbing, resting), the resort and the name of the piste or lift you are nearest to, your run count and total vertical for the day, whether the position is exact or approximate, and your battery level. Battery level is included because a friend seeing that your phone is nearly flat is useful information on a mountain.
Completed days, if you share them. When you turn on “Share completed days” we upload a summary of each recorded day to your account: the date, whether it was on skis or a snowboard, whether it was a resort or a backcountry day, when it started and ended, the run count, the total vertical and the distance skied. Not the recorded points, not the route, not the resort. This is off unless you enable it, and only the summaries recorded while it is on are counted.
Community totals. A group you belong to can choose to be listed in the community, on the Powe tab. Everyone with an account then sees that group’s name, picture and member count, and its totals for the season: days on snow, split into ski and snowboard days, runs and vertical. These totals are sums over the members who share their completed days; no member’s name, position or individual days are ever shown, and the database only returns the sums. Any member can remove the group from the listing, and switching off “Share completed days” removes your contribution immediately.
What we do not collect. There is no advertising identifier, no third-party analytics software development kit, no cross-app or cross-site tracking, and no contact list access in the app.
3. What stays on your device
Your recorded sessions are written to a database on your phone and stay there. That is deliberate: recording has to keep working with no mobile signal, which on a mountain is normal rather than exceptional.
Nothing leaves your device unless you turn on location sharing, or choose to share your completed days. Your sign-in session is held in the operating system keychain, encrypted by the device.
4. Who can see your location
Only people in the groups you choose, and only while sharing is on. The controls are:
Sharing is off by default. No groups, no automatic sharing.
Sharing expires automatically at the end of the ski day, so it cannot be left on by accident.
Ghost mode hides you immediately without leaving the group.
Approximate mode snaps your position to a coarse grid of roughly five hundred metres before it is sent, so it shows the area you are in rather than where you are standing.
Your position is only visible to people who share a group with you. This is enforced by rules on our database, not only by the app, so a modified app cannot read positions it is not entitled to.
We never show your email address, your preferences or your emergency contact to your groups. What other members see is your display name, username, photo, discipline and ability, plus your presence while you are sharing.
5. Legal bases for processing
Where the UK GDPR or EU GDPR applies, we rely on the following bases.
Performance of a contract, for your account, your profile and recording the days you ask us to record.
Your consent, for access to your device location and for sharing your position with a group. You can withdraw it at any time by turning sharing off, or by revoking the location permission in your device settings.
Our legitimate interests, for keeping the service secure and preventing abuse.
6. Service providers
We keep this list short on purpose. The providers we use to run the service are:
Supabase, which hosts our database, authentication and realtime messaging. Your profile, your presence while sharing, and any completed days you share are held there, in the TODO_BEFORE_LAUNCH region.
Google, which authenticates you when you choose to sign in with Google. Google receives the fact that you signed in to Powe. Google's handling of your Google account is governed by its own privacy policy.
Apple and Google, as the app stores that distribute the app and process any subscription payment. We do not receive or store your card details.
We do not sell personal data, and we do not share it with advertisers or data brokers.
7. International transfers
Our database is hosted in the TODO_BEFORE_LAUNCH region. Where personal data is transferred outside the UK or European Economic Area, we rely on the transfer mechanisms offered by the provider concerned, such as the European Commission's standard contractual clauses.
8. How long we keep things
Recordings on your device: until you delete them, or until you remove the app.
Live presence: transient. Your last known position is kept so friends can see where you were last seen, and stops being visible when the share expires.
Shared completed days: kept in your account until you delete your account, which removes them. While “Share completed days” is off they are not counted in any community total.
Profile and account: kept until you delete your account.
9. Your rights
Depending on where you live you may have the right to access a copy of your personal data, to have inaccurate data corrected, to have your data deleted, to receive it in a portable format, to object to or restrict processing, and to withdraw consent.
To exercise any of these, email TODO_BEFORE_LAUNCH. You can delete your account from inside the app at any time, which scrubs your profile and removes your presence and your shared completed days. You also have the right to complain to your data protection authority.
10. Children
Powe is not directed at children under 13, and we do not knowingly collect their personal data. Where local law sets a higher age of consent for data processing, that age applies instead. If you believe a child has given us personal data, contact us and we will delete it.
11. Security
Your sign-in credentials are stored in the operating system keychain. Traffic between the app and our servers uses encrypted connections. Access to your rows in our database is restricted by row-level security rules evaluated by the database itself, so authorisation does not depend on the app behaving correctly.
No system is perfectly secure, and we do not claim otherwise.
12. Changes to this policy
If we change this policy we will update the effective date at the top. If a change materially affects what we collect or who can see it, we will tell you in the app before it takes effect.
