These terms are the agreement between you and us about using Tjaz, and explain how we handle your personal data. Please read them: you accept them when you create an account, or when you make a quiz.
1Who we are
Tjaz is made and run by Allan Ebdrup, a private person in Denmark. There's no company behind Tjaz yet. In these terms, “we” and “us” means Allan Ebdrup, and “you” means you, who use Tjaz.
2Accepting the terms
You accept these terms when you create an account, or when you make a quiz without one. If you don't accept them, please don't use Tjaz.
If you use Tjaz for an organisation, e.g. a school or a company, you accept the terms on its behalf, and confirm that you're allowed to.
You must be at least 13 years old to create an account, which you confirm when you sign up. Anyone can take quizzes without one.
3What Tjaz is
On Tjaz you can make quizzes, lessons and courses, also with the help of AI, and share them with others.
Tjaz is free for now. We may add paid plans later. Their prices and any extra terms are shown before you choose a paid plan, and you never pay for anything you haven't chosen.
We do our best to keep Tjaz running, safe and useful, but Tjaz is provided as it is. We can't promise that it's always available, that it has no errors, or that nothing is ever lost, so keep your own copies of what matters to you.
We may change Tjaz, e.g. add, change or remove features, and limit how much it can be used, e.g. how many quizzes can be made in an hour. We may also close Tjaz. If we do, we tell you at least 30 days before, so you can save what you've made.
4Your account and organisation
Give correct details when you sign up, and keep your password to yourself. You're responsible for what's done with your account, so tell us right away if you think someone else has used it.
When you sign up, you get an organisation of your own, which you're the admin of, unless you've been invited to someone else's. Admins decide who's in their organisation, and can invite, change and delete its users. Everyone in an organisation can see all its quizzes, lessons and courses, and make new ones. Only the person who made a quiz can edit and delete it, while everyone in the organisation can edit and delete its lessons and courses. When a user is deleted, whoever deletes them chooses who in the organisation gets the quizzes they made.
5Your content
What you make or add on Tjaz, e.g. quizzes, texts, pictures and course material, is your content. You keep the rights to it.
You give us permission to store, copy, translate, adapt and show your content, as far as it's needed to run Tjaz and its features, e.g. to make a quiz from your course material, or to show your quiz to the people who take it. The permission is free, worldwide and not exclusive, and lasts as long as the content is on Tjaz, and for the copies others have made of it, see below.
Only add content you have the right to use, e.g. not a book, pictures or someone else's course material without permission.
Don't add personal data about other people, e.g. pupils, colleagues or customers, unless you're allowed to, and never sensitive personal data, e.g. about health, religion or sexuality.
You're responsible for your content. If someone makes a claim against us because of your content, or because you've broken these terms, you must cover our reasonable costs, as far as the law allows.
We don't sell your content, and we don't use it for advertising.
We may remove content, hide it from the quizzes page or block access to it, without asking you first, if we believe it breaks these terms or the law, or if someone reports it with good reason.
6Sharing and public quizzes
Anyone who has the link to a quiz can take it.
Quizzes made with AI without an account are public: they're listed on the quizzes page, where anyone can find and take them, and people who are logged in can copy them and change their copies. By making a quiz with AI without an account, you allow this, also after you've stopped using Tjaz. A quiz you make while you're logged in, with AI, from scratch in the editor or as a copy, isn't listed on the quizzes page unless you make it public, which you can change when you share it. By making a quiz public, you allow what's said above for it, until you make it not public again.
Lessons and courses can only be seen by your organisation, unless you make them public.
People who take a quiz can rate it, and the ratings are shown with the quiz on the quizzes page.
7Quizzes made with AI
Tjaz uses AI to make quizzes and to translate them. AI can make mistakes: an answer marked as right can be wrong, a fact can be out of date, and a text can be unsuitable. Check a quiz before you use it, especially for teaching, training or anything else where mistakes matter.
Quizzes on Tjaz aren't professional advice, e.g. medical, legal or financial advice.
You're responsible for how you use the quizzes you make and share, also the parts made by AI.
The AI is from Anthropic in the USA. What you ask it to make a quiz from is sent to it: the description, the settings and any course material you add, and the texts of a quiz you translate. Don't include personal data in it. Course material you add is kept with your account, under Source material, until you delete it there; when your account is deleted, it goes with your quizzes to the one in your organisation who gets them, or is deleted if you're the last one in it. It's sent to the AI again when a question in a quiz made from it is checked. The AI also checks that what you ask it to make a quiz from is within these terms, and if it isn't, the quiz isn't made.
A quiz that's written or changed in the editor is also checked against these terms by the AI, with its pictures, when it hasn't been changed for 10 minutes. If it isn't within them, others can't take, find or copy it until it has been changed, and the person who made it is told why by email.
When someone reports an error in a question or a fact in a quiz made with AI, the AI checks it, and corrects the quiz if it's wrong. If many of those who answered the question report it, it's replaced by a new question.
These checks are made automatically, and no person looks at them. If you think the AI is wrong, write to help@tjaz.com, and a person at Tjaz will look at it.
Quizzes made with AI say so when they're taken, also copies of them.
8What you mustn't do
Don't use Tjaz to:
- break the law or other people's rights, e.g. their copyright or privacy
- make or share content that's hateful, harassing, violent, sexual or harmful to children, or that's meant to mislead
- send spam, scams or harmful software, or link to them
- pretend to be someone else
- get into accounts or data that aren't yours, or break, overload or get around Tjaz's security or limits
- copy Tjaz or its content automatically, e.g. with scrapers or bots
We may block or close an account that breaks these terms, or that we must close by law, if necessary without warning. You can report a quiz that breaks the terms or the law with the Report quiz button in it, or by writing to help@tjaz.com.
A person at Tjaz looks at every report. When we remove a quiz someone made with their account, we email them why, and how they can object. If you gave your email when you reported it, we tell you what we decided.
9Your personal data
This section is about the personal data of everyone who uses Tjaz, also when you take a quiz without an account and haven't accepted these terms.
We're responsible for the personal data we process about you, which makes us the data controller. We process it according to the EU's General Data Protection Regulation (GDPR) and Danish law.
The personal data we process:
- Your account: your email address, your name, what you plan to use Tjaz for, your organisation and your role. Your password is stored so that no one can read it, not even us. If you turn on a passkey, we keep its public key, which can't be used to log in, the kind of device it was added on, e.g. iPhone, and when it was added and last used, and its backup code is stored so that no one can read it.
- What you make, and the answers you give to quizzes and lessons, which are saved with your account when you're logged in. Answers to quizzes are also saved when you aren't logged in, without your name, e.g. how long each question took, the rating you gave, and whether you played in 2D or as a 3D game, which we use to see how Tjaz is used and make it better.
- Technical data, e.g. your IP address, which is used to stop misuse, e.g. by limiting how many quizzes can be made. We keep it for an hour at most, and our hosting provider keeps it in its logs for up to a year. When you log in, sign up, change your password or email address, or turn a passkey on or off, we also write in those logs what happened and your account's id, but never your email address or password, so we can spot attacks on accounts.
- If you report a quiz: what you write, and your email if you give it, so we can tell you what we decided.
- If you write to us with Help and feedback: what you write, the page you wrote it from and which browser you use, so we can help you, and our answers. If you're logged in, also your account, and if you're a grown-up who gives your email, your email, so we can answer you. It's deleted two years after the last message, or sooner if you ask.
- If you challenge a friend from the end of a quiz: how many you got right, and the nickname you write, if you write one, which your friend and anyone the link is passed on to can see. It's deleted after 30 days.
- If you play a quiz together on a big screen: the nickname you write, which everyone in the game sees on the big screen, your answers and points, and a token kept in your browser, so you come back as the same player if the connection is lost. They're deleted a day after the game, and only how many played is kept, without names.
- If you use Tjaz in Slack, or get a quiz from it there: see “Tjaz in Slack” below.
Why we process it, and the legal basis:
- To give you Tjaz and your account, and to send you emails about your account, e.g. to verify your email address. It's necessary for our agreement with you (GDPR article 6(1)(b)).
- To keep Tjaz safe, stop misuse and make Tjaz better, e.g. from what users plan to use it for. It's our legitimate interest in running a safe and useful service (article 6(1)(f)).
- To follow the law, e.g. bookkeeping rules if we add paid plans (article 6(1)(c)).
We don't use your personal data for advertising, and we don't sell it. The only decisions that are made automatically are the AI's checks of quizzes, see Quizzes made with AI, and of the nicknames of challenges and of games on a big screen, and a person at Tjaz looks at one again if you ask.
To help you, or to stop misuse, the people who run Tjaz can see Tjaz as you see it when you're logged in, and can delete quizzes that break these terms. It's only done when it's needed, and it's logged.
Our suppliers, who store and process personal data for us:
- Scalingo in France hosts Tjaz and its databases, in France.
- Scaleway in France stores the pictures in quizzes, lessons and courses, and sends Tjaz's emails, in the EU.
- Google, through Google Ireland, receives the emails written to help@tjaz.com, and the messages written to us with Help and feedback. Google can process them outside the EU, e.g. in the USA, under the EU-US Data Privacy Framework and the EU's standard contractual clauses.
- Anthropic in the USA, whose AI makes, checks and translates quizzes, see below.
The AI from Anthropic gets what you ask it to make or translate a quiz from, the texts and pictures of quizzes that are written or changed in the editor, the questions someone reports an error in, what's written in a report of a quiz, to translate it into English, what you write to us with Help and feedback, to translate it into Danish, and our answers, to translate them into your language, and the nickname written for a challenge or a game on a big screen, to check that it's fine to show, e.g. that it isn't a full name or a rude word. It doesn't get your name or email address from Tjaz, but it gets any personal data in what it's sent, so don't put personal data in quizzes. Anthropic deletes it within 30 days, unless it's needed to stop misuse of its AI or by law. Anthropic's terms include the EU's standard contractual clauses, and say that it doesn't use what it gets from Tjaz to train its AI.
If you log in with Google, Microsoft, Facebook or Slack, they tell us your name and email address, and Slack also who you are in your organisation's Slack, see “Tjaz in Slack”. Their own terms apply to what they know about you.
We keep your personal data while you have an account. When your account is deleted, we delete your account details within 30 days, apart from what we must keep by law, and from backups, which are deleted after a while. The quizzes, lessons and courses of your organisation stay for the others in it, or are deleted with it, if you're the last one in it. Answers given without an account are kept without anything that tells who gave them. Reports of quizzes are kept, so we can see how a quiz was handled if it's reported again.
You have the right to see the personal data we have about you, to have it corrected or deleted, to have its use limited, to object to its use, and to get it in a format you can take elsewhere. Write to help@tjaz.com. You can also complain to the Danish Data Protection Agency (Datatilsynet) at datatilsynet.dk.
Tjaz' server also counts, hour by hour, how many see the front page, order a quiz, get it made, play it to the end and make an account, for each language, to see how Tjaz is used. These numbers say nothing about who: no cookies, no IP addresses and nothing from your device are used for them, so they aren't personal data.
10Personal data an organisation adds
When an organisation uses Tjaz for personal data about other people, e.g. when it invites colleagues, or collects answers from its employees or pupils, the organisation decides what the data is used for, and is its data controller. It's responsible for having a legal basis for the data, and for telling the people it's about.
We process that data on the organisation's behalf, as its data processor, only to run Tjaz according to these terms, which are the organisation's instructions to us. We keep the data confidential and secure, use only the suppliers above as sub-processors, and tell the organisation before we change them, so it can object. We help the organisation answer requests from the people the data is about, tell it without undue delay if the data is breached, and delete the data when the organisation stops using Tjaz.
Write to help@tjaz.com if your organisation needs a separate data processing agreement.
11Tjaz in Slack
You can connect Tjaz to your organisation's Slack and send quizzes to people there if you're at least 16. Slack is your organisation's own service, under its agreement with Slack (Salesforce, USA), and what Tjaz sends to Slack is stored where your organisation's Slack stores data. Slack's own terms and privacy policy apply to Slack.
When you connect Slack, we keep the workspace's ID and name, a key that lets Tjaz send messages there (encrypted), and who connected it. When you send a quiz, we keep who you chose to send it to, each person's Slack ID and name, whether it reached them, and, unless you send it anonymously, their answers, whether they were right and when they answered, so you can see how it went.
Slack also tells us who presses a button in Tjaz's messages, with their Slack ID and name, and sends us people's profiles (e.g. title and time zone) when we look up who's in a channel. We only use the ID, the name and whether they're a guest or from another organisation; we don't keep the rest.
In an anonymous quiz, we never store who gave which answers: answers are kept under a random number, with the day but not the time. We know who has answered, so we don't remind them, but the sender doesn't, and the sender sees results only when at least 5 have answered.
We process the data about the people a quiz is sent to on behalf of the organisation whose Slack it is, as its data processor (see “Personal data an organisation adds”). The organisation must tell its people about quizzes sent with names.
We never send anything from Slack to AI, never use it to train AI, never sell it and never use it for advertising, and we don't email the people who answer in Slack.
Names, Slack IDs and each person's answers are deleted when the sender deletes the quiz's send, and 12 months after its deadline at the latest; after that we keep only the totals without names. If someone says “Don't send me quizzes”, we keep only their Slack ID and that choice, so we can respect it. When Tjaz is removed from a workspace or its access is revoked, we delete the key at once and all of the workspace's Slack data within 14 business days.
Anyone who got a quiz from Tjaz in Slack can ask to see or delete their data at help@tjaz.com or with Help and feedback, without an account.
12Cookies
Tjaz uses these cookies, all for Tjaz itself. We don't use cookies for advertising or tracking.
- tjaz_session keeps you logged in, until you close the browser, or for a year if you choose to stay logged in.
- tjaz_lang remembers the language you choose, for a year.
- tjaz_quiz_owner remembers, for 5 years, that your browser made the quizzes you make without an account.
- tjaz_quiz_settings remembers, for a year, the settings you chose the last time you made a quiz, e.g. the tone and how many questions, and whether you had them folded out, but not what the quiz was about.
- tjaz_character remembers, for a year, how you designed your character in the 3D game.
- tjaz_oauth is used for a few minutes while you log in with Google, Microsoft, Facebook or Slack.
- tjaz_slack is used for a few minutes while you add Tjaz to Slack, and for an hour after, so the page you come back to can say which workspace you added it to.
- tjaz_impersonate is only used by the people who run Tjaz, for a few hours at most, while they see Tjaz as a user does.
Tjaz also keeps these in your browser, which aren't cookies:
- The answers to a quiz you take, so you can go on where you left off, also when you switch between 2D and 3D.
- playbackRate remembers how fast you chose to play the videos in quizzes.
- tjazQuizEnd remembers, until you close the tab, which page a quiz goes back to when it ends.
- tjazQuizDraft remembers, for a day at most, what you wrote and chose on the front page when you go to sign up or log in to add source material, so it's there when you come back. It's removed as soon as it's back.
- When you play a quiz together on a big screen, the token your phone joined the game with, so you come back as the same player, and on the big screen the game it shows, so it goes on if the page is opened again, until the game is over.
13Our liability
Tjaz is free, and is provided as it is. As far as the law allows, we're not liable for losses from using Tjaz or from not being able to use it, e.g. lost data, lost income, or the consequences of mistakes in quizzes, also ones made by AI or by other users.
If we're liable anyway, our liability is limited to the amount you've paid us for Tjaz in the 12 months before the loss, or DKK 500 if that's more.
We're not liable for delays or failures caused by things outside our control, e.g. failures at our suppliers, attacks on Tjaz, or power and network failures.
Nothing in these terms limits liability that can't be limited by law, e.g. for intent or gross negligence, or your rights as a consumer under mandatory law.
14Closing an account
You can stop using Tjaz at any time, and delete your account on your profile, or have it deleted by writing to help@tjaz.com.
We may close your account if you break these terms. We may also close an account that hasn't been used for 2 years, after telling you by email at least 30 days before.
15Changes to the terms
We may change these terms, e.g. when we add paid plans. If a change matters to you, we tell you by email or on Tjaz at least 30 days before it takes effect, unless it must happen sooner by law or for security. If you keep using Tjaz after that, you accept the new terms. If you don't accept them, you can stop using Tjaz and have your account deleted.
We may transfer the agreement with you, with your account and content, to a company that takes over Tjaz, e.g. one Allan Ebdrup creates to run it. We tell you if we do, and your rights under these terms stay the same.
16Law and disputes
Danish law applies to these terms. If we disagree, please write to us first, so we can try to solve it together.
Disputes are settled by the Danish courts, in the first instance by the City Court of Copenhagen (Københavns Byret). If you're a consumer in the EU, you keep the protection of the mandatory rules of the country you live in, and can also take a dispute to the courts there.
The terms are written in English and translated with AI. If a translation differs from the English version, the English version applies, as far as the law allows.
17Contact
Write to help@tjaz.com if you have questions about the terms or your personal data, or want to report content that breaks them.
help@tjaz.com is also Tjaz's point of contact for users and for the authorities under the EU's Digital Services Act. You can write to us in Danish or English, or in your own language, which we translate.
