  1. Section 01

    Who we are

    T-Invent, LLC (“we,” “us,” or “our”) is an independent app studio based in the State of California, United States. We make and run Adventure Guide.

    This Privacy Policy applies to Adventure Guide’s website, web app and related services (the “Service”). By using the Service, you agree to the collection and use of information as this policy describes.

    Our commitment: we do not sell your personal information, we do not show ads, and we collect only what we need to run the Service.

  2. Section 02

    Information we collect

    Information you provide

    • Your account: your email address, and your name if you sign in with Google. These are held by our sign-in provider, Clerk. Our own database keeps an account identifier, not your email address
    • The age check: your date of birth, which we use once to check that you meet our minimum age and never store or log. We keep only when you passed the check and the minimum age it was checked against
    • Your classes: their names, the teachers and contact details you add, office hours and help sessions, and dates such as tests and due dates, including those read from a syllabus you add
    • Your study material: photos of your notes, PDFs, slides, documents, typed notes, flash cards (including ones you import), video links and the transcripts you paste, your own presentation slides, and graded tests you add, including the grades and marks on them
    • Your answers and choices: practice answers, how you rate yourself, your answers to checks of your notes (including the corrections you write in your own words), the help you ask for, and a log of when you practised a hands-on skill, with any note you add, and each Again or Got it you give a flash card while studying, with when you gave it, and when each card is due again (used only to bring cards back when they're due, never as practice or for anything else)
    • Your settings: Dark mode, Calm mode, Trail level, school level, the time zone your device reports, how you like to study (such as pictures first or examples first), the reading and access needs you choose to set (easy-to-read text, plain language, extra time, or a screen reader), and the switches that decide what your guide is written from
    • Study groups, if you use them: the group names and nicknames you choose, which groups you're in, the notes you share with a group or hand to one member, group projects and their parts, your quiz answers and votes, and reports you send about a group or a member
    • Invites you send: the first name you choose to show and the class name, kept on the invite only while it's open and until your friend has set up the class it brings, and whether and when it was used. We don't keep your friend's email address
    • Reports you send about a quote, a question or a library item
    • Practice texts, if you turn them on: your mobile number, a one-time code we text to confirm it (we keep only a scrambled form of the code, and only until you confirm), when you confirmed it, the practice questions we text you, your replies (your answers, and words like HELP, MORE, DONE, STOP and START), and whether you've opted out
    • Your votes on the AI-made pictures for your topics and your map's areas
    • Tester feedback you choose to send with Tell us, which is stored with your account so we can follow up
    • Your agreements: which versions of these Terms and this Privacy Policy you accepted and when, and your confirmation before your first upload that your material is yours to study with and is processed by AI
    • Messages you send to our support team

    If someone invites you

    • Before you have an account, the email address you enter to get a sign-up link. We send it to Clerk and Resend to send you the link; our own database doesn't store it

    Information generated by the Service

    • What the Service makes from your material: the text read from your files and photos, topic maps, explanations, checks, practice questions and tests, feedback on your answers, study plans and help answers, each with the passages of your material it is based on
    • AI-made pictures for your topics and your map's areas, each with the passages it was made from. They're made from a short description our AI writes from your material, never from your files or photos, and they're labelled as AI-made
    • Your progress, worked out from the answers you keep
    • A summary of your practice over the last 90 days: how often you got each kind of question right, by format and skill, and how often your first guess on Check these spotted a mistake in your notes. You can see it under What your practice shows
    • Which part of a topic you turn to first (the picture, the 3D model, the lab or the summary), one record per topic and day
    • The results of our automated safety checks on what you add and what we generate
    • Usage records: for each AI request, the kind of request, the model used, how much text was processed and its cost. These records never hold your material or what the AI wrote

    Information collected automatically

    • Our hosting provider’s request logs, such as IP address, browser and device type
    • Our own error and activity logs, which record identifiers and counts and never your study material, what the AI wrote, or names

    Information we do NOT collect

    • Your date of birth (it is checked, not stored)
    • Payment information
    • Your location. We don’t ask for it. A photo file can record where it was taken if your camera adds that; we keep the file you upload as it is, but we don’t read or use that information, and the copy we send to our AI provider doesn’t include it
    • Your contacts or biometric data

  3. Section 03

    How we use your information

    We use the information we collect to:

    • Provide the Service: create and run your account, read your material, and build your guide, checks, practice and study plan, in your language
    • Write your guide for you: how you like to study, the reading needs you set, and your practice summary shape how your guide is written. Each can be turned off in More. Which part of a topic you turn to first is used only to suggest a study setting, and changes your guide only if you say yes
    • Run study groups and invites: show your nickname and what you share to your group, and the name and class on an invite link you send
    • Check your guide: work out what kind of class it is (its subject, level and notation) so your guide is written for it, then have each guide you build scored the way a subject expert would score it. What the review doubts goes to Check these; a guide it scores low may be rebuilt automatically, and the new one replaces yours only if it scores better
    • Make pictures for your topics and your map's areas from a short description of your material, and check them for safety and against your notes before you see them
    • Practice texts: send the practice questions you asked for by text, mark the answers you reply with, and send the replies to them. We text only the number you confirmed, at most the daily limit you agreed to, only between 8 AM and 8 PM your time, and never for advertising
    • See which classes and topics students study, so we can add pictures and models to our library. Our team sees class names and topic titles counted across students, never who made them, and never your notes
    • Keep the Service safe: check what you add, and what we generate, with automated safety checks, and hold flagged items for review by our team
    • Enforce usage limits and track what the Service costs to run
    • Help you: answer support requests and follow up on feedback you send
    • Updates: we may occasionally email you about changes to the app. Every update email has a link to unsubscribe, and unsubscribing doesn’t affect your account
    • Improve the Service: fix bugs and improve features, without training AI models on your material
    • Meet our legal obligations

    We do not use your information for advertising, we do not build advertising profiles, and we do not use your material to train AI models.

  4. Section 04

    How we share your information

    We do not sell, rent or trade your personal information. Your material and what is made from it are private to your account. Our team can see the names of classes and topics, counted across students and never with who made them (see How we use your information). Other people see only what you choose to show them: what you share with a study group or hand to one member (see Study groups and invites), and, on an invite link you send, the first name you choose and the class name. We share data only in these cases.

    Service providers

    These companies run parts of the Service for us and may use your data only to do so:

    • Anthropic (Claude): the AI that reads your material and writes your guide, checks your practice answers, writes the help you ask for, and runs our safety checks. We send it the material and answers involved, the class’s context, your school level and your language, and, while they’re turned on, how you like to study, the reading needs you set and your practice summary, written as how to write for you, never as a condition. We do not send your email address or account details. Under Anthropic’s commercial terms, it does not train its models on this data
    • OpenAI, xAI and Replicate: the AI that makes pictures for your topics and your map's areas. We usually ask OpenAI first, and xAI or Replicate when it can't make one. We send only a short description our AI writes from your material, checked first so it holds no one's name or contact details. We never send your notes, your files or photos, your email address, your name or your account details. Each of them may keep what we send and the picture it makes for a limited time under its own terms, for example to check for misuse. OpenAI and xAI don't train their models on it. The picture model Replicate runs for us is made by Black Forest Labs, whose terms let it use what it receives to improve its models
    • The U.S. National Library of Medicine’s PubChem service: confirms the structure of the chemical compounds named in a class’s notes. We send it only each compound’s name, never your notes, files, name or account details
    • TypeSafe (its Jev model), reached through Vercel’s AI Gateway: scores each guide you build the way a subject expert would. We send it your guide (its topics, formulas, practice questions, corrections, gaps and unclear spots), the passages of your notes it was built from, the class’s subject, level and notation, and your language. We never send your files or photos, your email address, your name or your account details. Every request is sent with zero data retention and no training on it, and only TypeSafe may answer it
    • Twilio: sending and receiving practice texts, if you turn them on. We send it your mobile number and the text of each message, and it gives us your replies. Your mobile carrier also handles these messages. Reply STOP to any of our texts to stop them all; reply START to turn them back on
    • Clerk: sign-in and account security. When someone you invite asks for a sign-up link, Clerk receives the email address they enter and holds it as an invitation
    • Vercel: hosting, and private storage for the files you upload
    • Neon: our database
    • Inngest: running the reading of your material and the building of your guide in the background. It receives identifiers of the work to do, not your material
    • Resend: email alerts to our team about how the Service is running, the occasional update email to you, which you can unsubscribe from, and the sign-up link a friend you invite asks for, sent to the address they enter. None of these contains your material

    When we add paid plans, Stripe will process payments. We will update this policy before that happens.

    Videos

    If you add a video link and press play, the video loads from YouTube’s privacy-enhanced player (youtube-nocookie.com), and YouTube’s privacy policy applies to it. Nothing loads from YouTube until you press play. We never download anything from YouTube; transcripts come from you.

    Legal requirements and safety

    We may disclose information if the law, a court order or a government authority requires it, or to protect the rights, property or safety of T-Invent, LLC, our users or others. We may report illegal content to the authorities, as the law requires.

    Business transfers

    If T-Invent, LLC is involved in a merger, acquisition or sale of assets, your information may be transferred as part of it. We will tell you before your data becomes subject to a different privacy policy.

  5. Section 05

    Study groups and invites

    Study groups

    Study groups are for students who passed our age check at 18 or older. In a group:

    • Other members see your nickname, what you share with the group, and what you do in it, such as your quiz answers, votes and project parts. They never see your email address, or your classes and files unless you share from them
    • Before you share, our automated safety checks read the text, and you see exactly what will be shared
    • What you share belongs to the group. It stays if you leave. If you delete your account, it stays without your nickname, shown as from a former member. Deleting the file or class it came from takes it out of the group
    • Notes you hand to one member are seen only by the two of you. They go when you take them back, when either of you leaves the group or deletes your account, or when you delete the file or class they came from
    • Group projects and their parts stay with the group. If you delete your account, your nickname goes from them
    • The group's organizer can remove a member. You can block a member, so you no longer see what they share, and report a group or a member to our team
    • A group's guide gets AI-made pictures too, made from the notes shared with the group, never from your own files. Every member sees them, and any member can mark one as not accurate, which removes it for the group

    Invites

    You can invite a friend to Adventure Guide, or to study a class with you, with an invite link. A link works once, and stops working after 14 days or when you revoke it.

    • Anyone who has your invite link can see the first name you choose to show and, for a class invite, the class name, without signing in. Nothing else of yours is shown: not your notes, your study group or its members
    • The link's preview in a chat app doesn't show your name or the class
    • Once the invite is revoked or expires, or once your friend has set up or skipped the class it brings, we delete the name and the class name from it
    • If your friend asks for a sign-up link, they enter their own email address, and we send it to Clerk, which holds the invitation, and Resend, which sends the email. Our own database doesn't store it. Clerk keeps a record of the invitation, with the address, after it stops working, and Resend keeps a log of the email under its own terms. To have Clerk's record deleted, email privacy@adventureguide.ai
    • A friend who signs up through a class invite gets their own class with the same name, in your study group if it has room. They can rename the class or leave the group at any time
    • We record which invite an account came in through. Only our team sees it

  6. Section 06

    Data retention and your choices

    We keep your information while your account is active or as needed to provide the Service. Specifically:

    • Your classes, files and everything made from them are kept until you delete them or your account
    • AI-made pictures are kept with the topic or map area they were made for, and deleted with the file they came from, the class or your account. A picture you mark as not accurate is deleted right away. OpenAI, xAI and Replicate may keep what they received for a limited time under their own terms
    • Your mobile number is kept until you remove it in the practice area or delete your account. Your text answers are kept like your other practice answers. Twilio keeps its own message records under its terms
    • Each version of your guide keeps a copy of the study settings, reading needs and practice summary it was written from, until the class or your account is deleted
    • When you delete a file, we delete it and everything made from it, such as the topics and questions that quote it, and older versions of your guide that used it are marked incomplete
    • When you delete a class, we delete the class and everything in it, including its files
    • When you delete a graded test, we delete it and its photos
    • When your account is deleted, we delete your account, everything it holds and your uploaded files, and your sign-in account with Clerk
    • Records of the agreements you gave, and the feedback you sent, are deleted with your account
    • Your invites are deleted with your account. An invite's name and class name are deleted once it's revoked or expires, or once your friend has set up or skipped the class it brings
    • When you leave a study group, your membership and nickname go, and what you shared stays with the group. When your account is deleted, you leave every group, and what you shared stays without your nickname
    • Your practice summary and the record of which part of a topic you turn to first cover only the last 90 days. Turning the second off in More deletes it
    • Usage and cost records are kept after your account is deleted, with nothing that links them to you
    • Deleted data may stay in our providers’ backups for a limited time, until those backups expire

    Get a copy or delete your account

    You can delete any file, graded test or class at any time in the app. To get a copy of your data, or to delete your account, email privacy@adventureguide.ai. We will do it within 30 days.

    Preservation of evidence

    We have the right, and sometimes the obligation, to preserve content and account records where the law requires it, including material we are legally required to report and preserve, and records under a legal hold or a lawful request from law enforcement. Where that applies, those records are kept even if you delete them or your account. They are stored separately, with restricted access, and used for no other purpose.

  7. Section 07

    Security

    We protect your information with measures including:

    • All data is encrypted in transit (HTTPS)
    • Our database and storage providers encrypt data at rest
    • Uploaded files are stored privately and served only to your signed-in account
    • Every request for your data is checked against your account
    • Access to production systems is limited to authorised people

    No method of sending or storing data over the internet is completely secure, but we take every reasonable precaution.

  8. Section 08

    Age and children’s privacy

    Adventure Guide is for people who meet the minimum age we set, currently 18. We ask for your date of birth before you create an account, and we don’t let anyone younger sign up. We do not knowingly collect personal information from anyone under the minimum age.

    The age check is a simple question, not a verification of who you are. If we learn that we have collected personal information from someone under the minimum age, we will delete it.

    Note for parents: if you believe your child is using Adventure Guide below the minimum age, contact us at privacy@adventureguide.ai and we will delete the account and its data.

  9. Section 09

    California privacy rights (CCPA / CPRA)

    T-Invent, LLC is based in California. California residents have the following rights regarding their personal information:

    • Right to correct: you can ask us to correct inaccurate personal information about you.
    • Right to opt out of sale or sharing: we do not sell your personal information or share it for cross-context behavioural advertising, so there is nothing to opt out of. You can contact us to confirm this at any time.
    • Right to limit the use of sensitive personal information: you can ask us to use sensitive personal information only as needed to provide the Service.
    • Right to non-discrimination: we will not treat you differently for using any of these rights.

    • Sensitive personal information: we don’t ask for it, but your study material may contain some; we use it only to provide the Service

    How to use your California rights

    Email privacy@adventureguide.ai with the subject line “California Privacy Request.” We will respond within 45 days, as the law requires. We may need to confirm your identity first.

  10. Section 10

    Cookies & tracking

    We use only essential cookies, which the Service needs to work:

    • Sign-in cookies from Clerk, which keep you signed in and protect your account
    • Age-check cookies, which remember the result of the age check without your date of birth: for one hour after passing, or 30 days after not passing
    • A language cookie, set only if you use the Service in a language other than your browser’s
    • Invite cookies, set only if you follow an invite link: one remembers the invite while you look around the sample class or answer the age check, until the invite expires (at most 14 days); another keeps your sign-up link for one hour while you answer the age check

    The app also keeps a few display choices in your browser’s own storage, such as the view you last picked for a picture. They stay on your device.

    We do not use analytics, advertising or third-party tracking cookies, so there is no cookie banner. You can block cookies in your browser, but you won’t be able to sign in without them.

  11. Section 11

    Third-party services

    The Service works with these providers. Each has its own privacy policy for the data it handles:

    • Anthropic: AI that reads your material and writes your guide
    • OpenAI, xAI and Replicate: AI that makes pictures for your topics and your map's areas
    • PubChem (U.S. National Library of Medicine): checking the chemical compounds your notes name, by name only
    • Twilio: practice texts (SMS), if you turn them on
    • Clerk: sign-in, and the invitations for friends you invite
    • Vercel: hosting and file storage
    • Neon: database
    • Inngest: background jobs
    • Resend: email alerts to our team, update emails, and sign-up links for invited friends
    • YouTube: the video player, only when you press play

    We store and process your data in the United States.

  12. Section 12

    The Adventure Guide for Canvas browser extension

    If you install our Chrome extension, Adventure Guide for Canvas:

    • It reads only the page you're on, and only when you press Read this page in its panel. You see what it found before anything is sent
    • It sends that page's text, and any files you tick (PDF, Word or PowerPoint), to your own Adventure Guide account, into the class you pick, only when you press Send. What it sends is handled like any notes you add (see "Information you provide")
    • To fetch a file you ticked, Chrome asks you once to allow the extension on that site. It then downloads the file as you, only when you press Send the ticked files
    • When you connect it, it sends a label for your browser (such as "Chrome on Windows") so you can tell your connections apart. It keeps a sign-in token for your account, and the class you picked for each course, in the extension's own storage. Disconnecting it on the Connect the Canvas extension page ends its sign-in; Disconnect this browser in its panel, or removing the extension, also clears what it stored
    • It never reads your Canvas password, grades or messages, never runs on pages you didn't choose, and sends nothing to anyone but Adventure Guide

    Our use of information received from the extension follows the Chrome Web Store User Data Policy, including its Limited Use requirements.

  13. Section 13

    Changes to this policy

    We may update this Privacy Policy as our practices, technology or the law change. When we make a material change, we will:

    • Ask you to read and accept the new version in the app before you continue using the Service

    If you do not agree to the updated policy, stop using the Service and ask us to delete your account.
