Subscription, Free Trial, Cancellation and Refund Policy
In brief. Paid plans renew automatically every month or every year until you cancel. You can cancel online at any time on the Your plan page, in a few clicks, and you keep everything you paid for until the end of the period. The 14-day free trial is free: cancel before it ends and you pay nothing.
This policy is part of our Terms of Service. It is offered by Mark T. Fulwider, doing business as TheoreticalPhysics.ai.

1.1. Prices are in U.S. dollars and do not include any sales, use or similar taxes, which will be added where the law requires and shown before you pay. The plans page always shows the current prices and what each plan includes before you buy.
1.2. A plan is for one person's use. Family accounts for children under 13 are described in Section 7.
2. The free trial
2.1. Each account may have one free trial of 14 days of a paid plan. Before the trial starts, we tell you the date it ends, the price that will be charged after it, and how to cancel.
2.2. Your payment method is not charged during the trial. Unless you cancel before the trial ends, your plan becomes a paid plan when the trial ends, and your payment method is charged the plan's price then and at the start of each later period until you cancel.
2.3. We will remind you by email before the trial ends. If you cancel during the trial, you are not charged, and the trial ends at once or at the end of the 14 days, as the cancellation page shows.
2.4. Free trials are not available to family accounts for children under 13 (Section 7) or to an account that has already had one.
3. Automatic renewal
3.1. Paid plans renew automatically. At the end of each monthly or yearly period your plan renews for another period of the same length, and the payment method on file is charged the plan's price then in effect, unless you cancel before the renewal date. Charges are made at the start of each period.
3.2. Your consent. Before your first payment (or before your trial starts), we show you these automatic-renewal terms clearly and ask for your express agreement to them, which you give by checking a box. We do not charge you without that agreement. We keep a record of it.
3.3. Acknowledgment. After you buy a plan or start a trial, we send you an email acknowledgment that repeats the automatic-renewal terms, the cancellation policy, and how to cancel, in a form you can keep.
3.4. Reminders. For a yearly plan, we send a reminder before each renewal that states the date and the amount that will be charged and how to cancel. At least once a year, for every paid plan, we send a reminder that states how often the plan renews, the amount charged, and how to cancel.
3.5. Payment problems. If a charge fails, the payment processor may try again over the following days, and we will tell you so that you can update your payment method. If payment cannot be collected, your paid features will stop until it is, and your plan may end. Your Work on your device is not affected.
4. How to cancel
4.1. Online, at any time. Sign in, open Your plan, and choose Cancel the plan (or Change card, plan, or cancel, which opens your payment processor's secure page). You do not need to call or write to anyone. You can also cancel a PayPal plan from your PayPal account, or ask us to cancel by writing to support@theoreticalphysics.ai.
4.2. When cancellation takes effect. Cancellation stops the next renewal. Your paid features stay open until the end of the period you have already paid for, and then end. We confirm every cancellation by email.
4.3. What happens to Your Work. Nothing. Your Work is on your device and stays there. If your plan included sharing, copies you shared stay available until they expire, and you may delete them at any time.
5. Refunds
5.1. Monthly plans. Monthly charges are not refundable, and partly used months are not refunded, except as Sections 5.3 to 5.5 provide.
5.2. Yearly plans. If you cancel a yearly plan within 14 days after a yearly charge (the first or a renewal), we will refund that charge in full. After 14 days, yearly charges are not refundable, and cancellation stops the next renewal.
5.3. Charges you did not intend. If you were charged after you tried to cancel, or were charged twice, or were charged because of an error on our side, write to support@theoreticalphysics.ai within 60 days and we will refund the charge.
5.4. Changes that reduce your plan. If we materially reduce what a paid plan includes, or close your account for a reason other than your breach of the Terms, we will refund the unused part of the current period.
5.5. Your legal rights. Nothing in this policy limits any right to a refund that the law gives you and that cannot be waived.
5.6. Refunds are made to the original payment method, usually within 5 to 10 business days of approval, depending on your bank or PayPal.
6. Changes of plan and of price
6.1. Changing plans. You can change to a different plan or cycle on Your plan. The payment processor's page shows any amount due or credit before you confirm.
6.2. Price changes. We may change the price of a plan. If the price of your plan changes, we will tell you by email at least 30 days before the change applies to you, and no less than 7 days before you are charged the new price, with the new price and the date it takes effect and how to cancel. The new price applies from your first renewal after that date. If you do not agree, you may cancel before the renewal.
7. Family accounts for children under 13
7.1. A family account for a child under 13 is held by the child's parent or legal guardian (see the Children's and Students' Privacy Notice). The parent's first payment verifies the parent's consent, so family accounts must choose a paid plan, and the first payment is charged when the plan is bought, without a free trial. All other parts of this policy, including cancellation and refunds, apply. A parent may cancel at any time and may ask us to delete the child's information.
8. Sharing allowance
8.1. The Desk Top + Study Hall plan includes up to 10 GB of shared copies stored at any one time per account. Your work kept on your own device does not count against it. If you need more, write to support@theoreticalphysics.ai; additional storage may be offered for an additional charge, which we will show you and ask you to agree to before you are charged.
8A. Using the app without internet
8A.1. The app works without internet. While offline, your plan is treated as paid until the date it was last confirmed as paid through, plus 3 days, and for no more than 30 days since the app last reached us. After that, until the app can confirm your plan online, it works as the free version: Study Hall and AI Record pause. Your work is not deleted or changed; it stays in your TP.AI folder and on your device, and the paid features return as soon as your plan is confirmed.
9. Payment processors
9.1. Payments are taken by Stripe or PayPal on their own secure pages. By paying, you authorize the processor to charge your payment method for the plan you chose, its taxes, and its renewals until you cancel. We never receive your full card number. If your card details change, update them on Your plan.
10. Questions
10.1. Write to support@theoreticalphysics.ai. California residents may also contact the Department of Consumer Affairs, as Section 18 of the Terms describes.
