Zemi Subscription Terms

Draft: not yet reviewed by a lawyer. Lawyer review is deferred by the owner (decision of 2026-10-26). This is not legal advice. Sections marked Draft are still being confirmed. Version 1.0, issued 2026-11-06.

Last updated: 2026-11-06
Effective date: 2026-11-06
Who we are: Zemi Learning Corporation (proposed corporate name; to be confirmed with the incorporation package), Ontario, Canada.

1. In short

Zemi is free to use, and every plan has every feature. A paid plan only gives you more hosted AI (the AI that runs in our cloud for you). Local AI and your own API key are always free and unlimited. Paid plans renew automatically until you cancel. You can cancel online in two clicks and keep what you paid for until the period ends. If you change your mind within 7 days of your first payment, we’ll refund you, no questions asked.

2. Plans

All prices are in US dollars. Taxes are shown at checkout, as section 11 explains.

These allowances are guarantees. The limits shown for the plan you bought are what you get for each billing period. If our costs fall, we may raise allowances. We will not lower the allowances of a plan you have already paid for during your current period. If we lower a plan’s allowances for new customers, you will get at least 30 days’ notice before it applies to your next period, and you may cancel first.

Diagrams, charts and plots are drawn on your computer, so they’re unlimited and don’t count.

3. How usage is counted

Draft (proposal, for the owner to confirm): a term is one of three calendar terms, in UTC: winter (January to April), summer (May to August) or fall (September to December). Education and Pro plans get the exam season bonus once per term (+300 answers for Education, +500 for Pro). You claim it in the app, and its answers can be used for 60 days from the claim. This matches current_term and grant_exam_bonus in the backend and the “once per term” rule in our pricing.

• One reply from the hosted AI is one answer, however long it is.
• Web lookups and AI illustrations have their own counters.
• Zemi always tells you before it uses a web lookup or an illustration.
• Your counters reset every month on your billing date (on the 1st for Free). Unused answers don’t roll over.
• The app shows your balance in the nav bar and in Settings > Plan & usage. The number you see matches our records.
• There is no hidden weekly cap. A gentle “on track / ahead of pace” hint is only a hint.
• Local AI and your own API key never count.

When you run out. Zemi tells you once, kindly, and offers three choices: switch to local AI, use your own API key, or upgrade. Nothing in progress is lost, and nothing is quietly made worse.

Exam season bonus. Education and Pro can add a one-off bonus of extra answers until 14 days after the entered exam date, once per term. A “term” is a 4-month period.

4. Renewal

• Paid plans renew automatically at the end of each period (monthly or yearly), for the same length and at the price shown when you bought, until you cancel.
• Before you pay, we show you: the price, how often you’re charged, the date of the next charge, that it renews automatically, and how to cancel.
• You must agree to automatic renewal on its own (a separate tick or button, not hidden inside other terms).
• The renewal date is shown in Settings > Plan & usage and on every receipt.
• Yearly plans: we email you a reminder before each yearly renewal (30 days before, decided 2026-10-27, meets California’s 15 to 45 days), with the price and how to cancel.
• We keep a record of your yes: when you gave it, the plan, the price, how often it renews, the reminder, and the version of these renewal terms you were shown. It is in your account data download (Settings > Privacy & data).
• Renewal terms version: 2026-10-27

5. Cancelling

• Go to Settings > Plan & usage, then choose Cancel plan, then confirm. Two clicks. No phone calls, no forms, no questions. If you bought through our website, you can also cancel from the Stripe customer portal link on your receipt.
• You can cancel at any time. It takes effect at the end of the period you’ve already paid for, and you keep your plan and its allowances until then.
• We won’t charge you again after you cancel. You’ll get an email confirming the cancellation and the date it ends.
• We may ask whether you’d like to pause or switch plans, but only on a single optional screen, and you can skip it with one click.

6. Downgrading and what happens after

• Downgrades (for example Pro to Education, or any paid plan to Free) take effect at the end of the billing period.
• When your plan ends you move to Free. Your courses, files, chats, memories and all features stay. Only the hosted-AI allowances change.
• If your plan is cancelled because your payment failed, we’ll email you first and try again over about 7 days (per Stripe’s standard retry schedule) before moving you to Free.

7. Upgrading

If you move to a more expensive plan part-way through a period, you pay the difference for the rest of the period (calculated by Stripe), your used counters carry over, and your new allowances start immediately.

8. Refunds

• 7-day refund. Ask within 7 days of your first payment for a paid plan and we’ll refund it in full. No questions. Applies once per account and per plan tier.
• After 7 days. Plan fees for a period that has already started are not refunded, except where the law says otherwise. Consumer protection laws in some places (for example Quebec) require pro-rated or other refunds in some situations, and we will follow them.
• If we end your plan for something that isn’t your fault (see the Terms of Service), or if the hosted service is down for 7 consecutive days or more, we’ll refund the unused part of what you paid for the period.
• If we charged you by mistake, or you were charged after cancelling, we’ll refund it.
• If we close an account because its age answer shows someone under 18, we cancel the plan at once and automatically refund the unused part of the current period to the original payment method. If this happens within 7 days of the first payment, we refund that payment in full.
• To ask, email billing@getzemi.tech or use the link on your receipt. Refunds go back to your original payment method and usually appear within 5 to 10 business days.

9. Price changes

We’ll give you at least 30 days’ notice by email and in the app before any price increase for your plan. We never change the price in the middle of a term you’ve already paid for. If you don’t agree to the new price, cancel before it starts and you’ll keep your plan until the end of the period you paid for.

10. Education plan

The Education plan is for current students and educators.

• How we check. Either a school email address (such as .edu, .ac.* or another school on our list, for example mail.utoronto.ca), or a photo of your student or staff card, which a person at Zemi reviews.
• Privacy. We collect the minimum. Card images are deleted as soon as they have been reviewed (and always within 14 days). See the Education verification privacy notice.
• Yearly re-check. We check again every year, before your Education plan renews. We’ll tell you at least 30 days beforehand and show you how.
• If you no longer qualify, or the check doesn’t pass. We’ll tell you why. A person can look at it again if you ask. We won’t switch you to a more expensive plan without your yes. Your Education plan ends at the end of the period you’ve paid for, and you can choose Pro or Free. If you do nothing, you move to Free.
• Don’t misuse it. Giving false details to get Education pricing is against our rules and can lead to the plan being closed.

11. Payments and tax

• Payments are handled by Stripe by card (and any other methods shown at checkout). We never see or store your full card number.
• Prices are in US dollars. Your bank may charge a foreign-exchange fee. Zemi may show prices in your local currency for information.
• Taxes (like GST/HST in Canada, and US sales tax where required) are calculated by Stripe Tax and shown at checkout and on your invoice.
• Invoices and receipts are in Settings > Plan & usage.
• Zemi is for adults (18 and older), in every region. There is no parent or guardian route: the person who makes the account buys the plan.

12. Changes to these terms

If we make a material change we’ll tell you at least 30 days beforehand. If you don’t agree, you can cancel before it starts and keep your plan until the end of the period.
