Privacy policy
Last updated: 17 October 2026
Proskida Inc. ("Protern", "we") provides Protern Web, Protern Video, Protern Sync, Protern Clock, the Protern Sensor and the store at protern.io (together, "the services"). This policy explains how we handle personal data in them.
1. Who is responsible
When you sign up yourself, Protern is the controller of your data. When a club, team or federation has you use Protern, that organization is the controller of your training data and videos, and we process them on its behalf. For requests about that data, contact your organization; if you contact us, we pass your request on.
Contact: privacy@protern.io, or Proskida Inc., 2180 2nd Ave, Whitehorse, Yukon Y1A 2A8, Canada.
EU representative under Article 27 GDPR: Europe Services, SE, Na Cecelicce 425/4, Smichov, 150 00 Praha 5, Czech Republic. Data subjects may contact the representative at info@gdprrepresentative.com regarding the processing of their personal data.
2. What we collect, why, and on what basis
| Data | Purpose | Legal basis |
|---|---|---|
| Account details: name, email, password, role, date of birth | Provide your account and the services | Contract |
| Training data: position, speed and motion from the Protern Sensor or uploaded files, and the results we derive from them | Provide the analysis | Contract |
| Videos, and who has viewed them | Provide video review and sharing | Contract |
| Physiological data you choose to enter, such as weight or para-athlete classification | Put your training in context | Your explicit consent, which you withdraw by removing the data |

Coaches and clubs can add athletes who have no account; we then receive the athlete's name and training data from them.
We also use data to improve the services and to produce aggregated or de-identified statistics, in our legitimate interest in better products. We do not sell personal data or use it for advertising.
Account and training data are needed to use the services; everything else is optional.
3. Children
If you are under 16, you can use Protern only through a club or team that has your parent's or guardian's consent, or with an account your parent or guardian has created or approved.
4. Who receives your data
The people you share with in the services: your coaches, linked parents and team. And service providers that act only on our instructions, under contracts that require them to protect the data. The main ones are below; the full list is at protern.io/pages/subprocessors.

5. International transfers
Your data is stored and processed outside the European Economic Area, including in the United States, Canada and Switzerland. Canada and Switzerland have EU adequacy decisions. For the United States we rely on the EU-US Data Privacy Framework or the European Commission's standard contractual clauses. You can ask us for a copy of the safeguards.
6. How long we keep data
As long as your account exists, or until you or your organization delete the data. Billing records are kept as long as tax law requires. Backups and crash reports are kept for a limited time, and backups are used only to restore the services.
7. Your rights
You can ask to access, correct, delete or receive a copy of your data, to restrict or object to how we use it, and to withdraw consent at any time. Email privacy@protern.io; we answer within one month. If your organization is the controller (section 1), we pass your request to it.
You can also complain to the data protection authority where you live or work.
8. Security
We protect your data with encryption in transit, access controls and restricted staff access. If a breach puts your data at risk, we notify the authorities and you as the law requires.
9. Cookies
Our web app uses only the cookies it needs to sign you in and remember your preferences, and no analytics or advertising cookies. Our website and store at protern.io use the cookies the store needs to work and, if you accept them in the cookie banner, analytics cookies. You can change your choice at any time from the banner.
10. Automated decisions
We make no decisions about you with legal or similarly significant effects by automated means.
11. Changes
We post changes here with a new date, and tell you by email or in the apps before a significant change takes effect.
