Privacy policy

This policy says what we collect, why we are allowed to, who else ever sees it, how long we keep it and what you can make us do about it.

The short version: we do not sell your data, we show no advertising, and we run no analytics or tracking.

1. Who is responsible

Interval Labs BV, registered with the Dutch Chamber of Commerce (KvK) under number 42139840, at Herengracht 551, Amsterdam, is the controller of the personal data described here. Write to hello@intervallabs.nl about anything in this policy.

2. What we collect

Your account. You sign in with Apple, and we receive an identifier for you there, plus your email address and your name if you let Apple pass those on. We also keep a token Apple gives us at sign-in, which we use only to tell Apple when you delete your account. We store no password. We keep the language and time zone of the device you made your account on.

Your devices. For each phone or browser that is signed in we keep an identifier for it, the name it gives itself, its language, when it signed in, when it last reached us and the IP address it last reached us from. The app also tells us the phone's model, system version and time zone, and we keep those too; a browser does not send them. If you turned notifications on, we also keep the token Apple gives us for reaching that phone.

Server logs. Our server writes a line for each request: the time, what was asked for, the IP address it came from, and which account made it, if any. We use them to keep the service running and to investigate abuse.

No law obliges you to give us any of this, and no contract obliges you either. Without an Apple sign-in there is no account, though. If you would rather not give it, the consequence is that you cannot use Bliep.

3. Cookies

We do not track you. The website sets four cookies and every one of them is there to make it work: one keeps you signed in, one recognises your browser so a second sign-in replaces the first rather than piling up, one lasts the few minutes a sign-in takes, and one carries a message such as "That device is signed out." to the next page for a minute. There are no analytics or advertising cookies, and nothing follows you to another site. That is why you are not being asked to accept anything.

4. Why we are allowed to use it

• To run Bliep for you, because you asked us to and that is our agreement (GDPR article 6(1)(b)).
• To keep the service secure, available and free of abuse, which is our legitimate interest and yours (article 6(1)(f)).
• When the law requires it of us (article 6(1)(c)).

We make no automated decision that has a legal effect on you or anything like one.

5. Who else sees it

• Apple, who you sign in with. They learn that you signed in to Bliep.
• Apple, when we send a notification to your phone. A notification carries the text you would read on the lock screen.
• Scaleway, who host the server and the database for us in the Netherlands.
• Authorities, if the law obliges us. We will tell you it happened unless we are forbidden to.

Nobody else. We do not sell personal data, we do not pass it to advertisers or data brokers, and we do not use it to train anything.

6. Where it is kept

Everything lives in the Netherlands: the server, the database and the continuous backup of the database. Two exceptions leave the EU by their nature. Signing in involves Apple, and notifications go through Apple's push service. Apple is an American company, and the safeguards it applies to those transfers are the ones it publishes itself, in Apple's privacy policy and the transfer terms it names there.

7. How long we keep it

• Your account and everything in it, for as long as your account exists.
• Server logs, two weeks, then they are deleted.
• The continuous backup of the database, 30 days. A deletion reaches the live database at once and is gone from the backup within a month.

Deleting your account deletes your account details and your devices. You can do it yourself in the app, or ask us at hello@intervallabs.nl.

8. Your rights

Under the GDPR you can ask us for a copy of what we hold about you, have it corrected, have it deleted, have our use of it restricted, receive it in a portable form, and object to our using it. Write to hello@intervallabs.nl and we will answer within a month. It costs you nothing.

If we handle it badly, you can complain to the Dutch data protection authority, the Autoriteit Persoonsgegevens (autoriteitpersoonsgegevens.nl), or to the authority in the EU country you live in.

9. Age

An account is for people of 16 and over. That is the age at which you can consent to this yourself under Dutch law. If we find out an account belongs to someone younger, we delete it.

10. How we protect it

Traffic between your devices and us is encrypted. We keep no passwords, because Apple holds them. Each phone or browser has its own session, and signing out of the website ends that session on our side, not just in the browser.

11. Changes to this policy

We may change this policy. If a change matters to you, we will tell you at least 30 days before it takes effect, by email or in the app, and the date at the top always says when this version was written.
