Puck and the six drawers

Privacy at Puck

Puck and the six drawers is an app that goes with Maria de Ridder's books about AnnaMaria and Puck. This page tells you what happens to your data when you use Puck or make an account for it. What is not here is in our platform's privacy policy, which applies to Puck as well.

Who we are

Puck runs on the MindfulnessInc platform, part of Buddha in the Boardroom, the Dutch sole proprietorship of Koen van den Biggelaar (Chamber of Commerce 96493798). We are responsible for your data. Maria de Ridder wrote the books.

Who Puck is for

Puck is for adults with a question from daily life: about a partner, a neighbour, work, a friend, the family, a parent growing old, yourself or a child. An account is only for people aged 18 or over. Do not make one for a child. If a child writes to Puck, Puck says it is here for grown-ups and starts no conversation.

What is yours stays yours

  • What you share with Puck and keep in your cabinet is yours and personal. With an account, Puck keeps it on our platform: per person, encrypted, on servers in Frankfurt. That way Puck can remember you and look back with you.
  • Nobody reads along. Maria only sees how often Puck is used, in totals of at least five people. Never per person, and never what anyone wrote, unless you send it to us yourself. There is one exception to the rule that nobody reads along: if violence at home or danger to a child comes up, the makers of Puck may read that one conversation. How that works is below.
  • We use no tracking cookies.
  • Anything that is still only on your phone stays there until you choose to bring it to our platform. What is on your phone is left out of backups to iCloud or to your computer.

Trying Puck without an account

  • In the app you can first talk with Puck without an account: a few replies from Puck, after which you can make an account to go on.
  • We keep nothing of such a trial conversation on our platform. The conversation travels with the app, encrypted, and is opened only to give the next reply. After a day it cannot be continued. To answer, it goes to Anthropic, as every conversation does.
  • To keep it fair we count trial conversations: per day, per device (with a random code the app makes itself) and per internet address (only as an unrecognisable code). These counts hold no text and are erased within 30 days.
  • If you then make an account, the trial conversation comes along and Puck keeps it there like any other conversation. If you do not, nothing of it is left afterwards, not for the makers of Puck either.

When you talk with Puck

  • When you talk with Puck, what you write goes to our platform. There Puck keeps the conversation for 90 days. After that it is erased by itself.
  • Every message carries: the language of the app, and the country, if your phone is set to the Netherlands or Belgium. That way Puck knows, for example, which holidays are coming.
  • What Puck keeps in your purple drawer on our platform goes with your conversations, so that Puck can come back to it.
  • To answer, our platform sends the conversation to Anthropic, which provides the language model. When Puck looks something up, for example to check a fact, the search goes through Anthropic's search service.
  • When you speak to Puck, Amazon Transcribe in Frankfurt turns your voice into text as you talk. The audio is never stored, not on our platform and not on your phone: only the text becomes part of the conversation, just like what you type. When you let Puck answer aloud, Amazon Polly in Frankfurt makes that sound from the text of the reply. That audio is not stored either. Puck's voice is a standard Amazon voice, not the voice of a real person.
  • Puck is not a helpline, but it does not look away either. If what you say shows that you or someone else may be in danger, Puck takes it seriously, says that it is an AI and names in the conversation where you can turn: in the Netherlands 112, 113 Zelfmoordpreventie, Veilig Thuis or the Kindertelefoon; in Belgium 112, Zelfmoordlijn 1813, 1712 or Awel. If Puck names Veilig Thuis, 1712, the Kindertelefoon or Awel, because violence at home or danger to a child comes up, the makers of Puck at MindfulnessInc are told, and may read that one conversation, so that a person can see what is needed. That is the one exception to the rule that nobody reads along, and Puck says so in the conversation. With the other helplines nobody reads along. In an emergency the makers may contact Veilig Thuis or 112 themselves. What you do with what you know remains for you.

The purple drawer: what you want to take with you

  • What you keep in the purple drawer of your cabinet, Puck keeps encrypted with your account on our platform, for you only. That way Puck can come back to it in a later conversation.
  • When you talk with Puck, at the end of the purple drawer you sum up for yourself what you want to keep. Puck then asks one thing: "Is this something you want to remember and take with you?" Say yes, and your summary, in your words and dated, goes into your purple drawer. Say no, and Puck does not keep it: it is then only in the conversation.
  • If you kept something in the purple drawer on your phone before, it stays there. Puck asks you once whether it may go into your purple drawer with Puck. Only if you say yes does it go to our platform.
  • Nobody reads what you keep, and it is used for nothing but your conversations with Puck.
  • You always see it in the app, in the purple drawer. You can change or delete it, line by line or all at once, and you can receive it as a document.
  • When you have kept something new, Puck invites you in a conversation to look back together at what you kept. Puck does this every week or every month, as you choose.
  • It stays until you delete it: it does not expire after 90 days like a conversation. It comes along when you download what we keep about you, and it is erased when you have Puck forget you or delete your account. Before you do, Puck asks whether you want to take it with you first.

Getting to know you, the morning question and how it is going

  • With an account, Puck first asks you a few questions to get to know you: who you feel responsible for and who you are to them, what you come to Puck for and what you would like to mean. You may skip them and change them later in the app. Your answers are stored encrypted with your account on our platform. Only Puck uses them: they go with your conversations, so that Puck knows who you come for. Koen and Maria see only how many people answered, never what.
  • Puck also asks whether you would like a question from Puck in the morning. We keep your yes or no with your account. You switch it on or off in the app.
  • After a few weeks Puck asks whether you are getting what you came for. Puck uses your answer in the conversation. Koen and Maria see only how many people chose yes, partly or no. A line you add is seen by them only if you tick that it may go to the team; it then reaches them with your name.

Who processes your data for us

  • Amazon Web Services in Frankfurt (Germany): our platform, storage, sign-in, the emails we send, and turning your voice into text and the replies into sound.
  • Anthropic in the United States: the language model that writes Puck's replies, and the search service. Anthropic does not use this data to train its models and keeps it only for a limited period.
  • Apple, if you put Puck on your iPhone through TestFlight.
  • Google, if you put Puck on your Android phone through Google Play.
  • Microsoft for our email.

Transfers to the United States are covered by the European Commission's Standard Contractual Clauses and, where the provider is certified, the EU-U.S. Data Privacy Framework.

Your account

  • In the app you make an account yourself, with your email address and the confirmation that you are 18 or over. You receive a code by email to sign in with; no password is needed. Such an account opens at once, without approval, and you receive a welcome email. To prevent misuse we count how often an account is asked for, per day and per internet address, also when it does not succeed; that address is held only as an unrecognisable code, and for a few days.
  • If you install on Android, you email us the Google account on your phone. We use it only to put you on the test list for the Android app, at Google Play. If you want it off, email us.
  • Until November 2026 you could request an account on this site. If you were given an account then, what you filled in belongs to that account. If you were not, what you filled in has been erased. A code derived from your email address is kept for 90 days after the decision.
  • Sign-in is handled by Amazon Cognito. We never see your password.

Face ID

If you choose to sign in with Face ID (or Touch ID, or your fingerprint), your session stays on your phone, behind Face ID. Your password is never kept on your phone. Your face or fingerprint never reaches us: your phone handles that itself. You can also lock the app. That lock lives on your phone only.

Erasing

What is on your phone and what Puck keeps on our platform are erased separately in the app.

  • On your phone: if anything is still there, you erase it under Account, with "Erase what is on this device". Face ID for Puck and the lock are switched off as well.
  • In the purple drawer: there you delete what Puck keeps for you, line by line or all at once.
  • On our platform: under Account, at "Forget me on Puck". That erases your conversations with Puck, your profile there, what is in your purple drawer, and your access. At "Delete account" you also remove your login. This does not erase what is on your phone.
  • Under Account you can also download what we keep about you.

Your rights and contact

You have the right to see your data, to have it corrected or erased, and to object. Much of this you can do yourself in the app. For anything else, and for questions, write to koen@mindfulnessinc.org. We answer within one month. If you are not satisfied with how we handle your data, you can complain to the Dutch data protection authority, the Autoriteit Persoonsgegevens.
