Terms of Service
These terms cover your use of MindVault: the website, the mobile app, and the browser extension. Using MindVault means you agree to them.
Your account
You need an account to use MindVault, you must be at least 13 years old, and the information you give us must be accurate. You are responsible for what happens under your account, so keep your credentials to yourself.
Your content stays yours
Everything you save is yours. You grant us only the permission needed to run the service: to store your content, to send it to the language-model providers named in our Privacy Policy so it can be turned into concepts and quiz questions, and to show it back to you. We do not use your content to train models, and we do not publish it.
Do not save content you have no right to save, and do not use MindVault to store or share anything unlawful.
A young service
MindVault is new and changing quickly. Features will change, and downtime and bugs are possible. Do not use it as the only copy of anything you cannot afford to lose.
Subscriptions
MindVault is free to use with a daily limit on quizzes. MindVault Pro and MindVault Unlimited raise that limit and are sold in the iPhone app as auto-renewing monthly subscriptions through Apple. The price, and any free trial, is shown in the app before you buy.
Payment is charged to your Apple Account when you confirm the purchase. A subscription renews automatically each month at the same price unless you cancel it at least 24 hours before the end of the current period, and your account is charged for the renewal within the 24 hours before that period ends. You can manage or cancel it at any time in your iPhone’s Settings, under your name, then Subscriptions. Canceling stops the next renewal; you keep what you paid for until the period ends. If you start a paid subscription during a free trial, the rest of the trial ends. Refunds are handled by Apple under its own policies.
Unlimited has no daily quiz limit for ordinary study. Automated or abusive use is not ordinary study (see Fair use below). We may change plans and prices; a price change never applies to a period you have already paid for, and Apple tells you before a renewal at a higher price.
Written by AI
Much of what MindVault shows you is written by a language model: the concepts it draws from what you save, quiz questions and answers, and Learn’s course outlines and lessons. A Learn course is written from the official course record or from a student’s syllabus. It is not your instructor’s syllabus. AI can be wrong, so check anything that matters against your own course materials.
Sparks and unlockable items
Sparks are an in-app currency earned by studying. They cannot be purchased, they have no cash value, they cannot be transferred or redeemed for money, and any sparks or items in your account disappear when your account does. We may adjust prices, rewards and the catalog at any time.
Fair use
Do not attempt to break, overload, or reverse-engineer the service, do not automate access to it, and do not use it to abuse or harass other people. We may suspend or terminate an account that does.
There is no tolerance for objectionable content or abusive users. Names, profiles and anything shared with other people must not be hateful, sexual, threatening or harassing. Report a person or a question from the menu beside it, or block them; we review reports within 24 hours and remove the content, and the account that posted it, where it breaks these terms.
Ending it
You can delete your account at any time from inside the app; see the Privacy Policy for exactly what that erases. We may suspend or end your access if you breach these terms or if we stop operating the service.
No warranty, and limits on liability
MindVault is provided “as is”, without warranties of any kind. To the extent the law allows, we are not liable for indirect or consequential damages, or for lost data or lost profits, arising from your use of the service.
Changes
We may update these terms. Material changes will be announced in the app, and the effective date above will change.
