Primordia is free to install and use. The free tier keeps one grow going at a time; finishing a grow frees the slot for the next one. Backup and restore are free for everyone, permanently — with no cloud sync in this app, the way to get your records off the device is not something we will ever charge for.

Primordia Pro is sold three ways: a monthly subscription, an annual subscription, or a one-time lifetime unlock. All three grant the same thing. The current price for each is shown on the upgrade screen in the app and on your store's product page before you confirm — those are the prices that bind, not any figure quoted elsewhere on this site.

Pro currently unlocks:

We may add to that list, and we may change or retire a feature within it. If we remove something material from Pro we will say so in the app first. The upgrade screen in the version you are running is always the authoritative description of what you are buying.

We never handle your money. Primordia has no payment system, no card details and no invoices. You buy Pro from Apple's App Store or Google Play, they charge the payment method on your store account, and they are the merchant of record for that transaction.

Renewal. The monthly and annual plans renew automatically at the end of each period, at the then-current price, until you cancel. Apple and Google require cancellation at least 24 hours before the period ends for it to take effect on that renewal. The lifetime unlock is a single charge — it does not renew, and there is nothing to cancel.

Cancelling. Cancel in your store account, not in Primordia — we have no ability to cancel a subscription on your behalf, and no visibility into your billing. The app's Manage subscription row opens the right screen for you, or go directly to your Apple subscriptions or your Google Play subscriptions. Cancelling stops future renewals; Pro stays active until the period you already paid for runs out.

Refunds. Refunds are Apple's and Google's to grant, under their own policies — we cannot issue one, reverse a charge, or override their decision. Request one at reportaproblem.apple.com or through Google Play's refund process. Write to us anyway if something went wrong: we can often explain what happened, and we would rather know.

Price changes. If we change the price of a subscription, the store handles notifying you and, where their rules require it, asking for your consent before the new price is charged. A lifetime unlock already bought is unaffected by a later price change.

Restoring a purchase. Pro is tied to the App Store or Google account that bought it, not to a Primordia account — there is no such thing. On a new phone, sign in to the same store account and use Restore purchases in Settings. If you buy on iOS, that purchase does not carry over to Android, or the reverse; the two stores are separate.

Some of what governs your purchase is not ours to write, and saying so plainly matters more than pretending this page covers everything:

Apple. Your use of the app on iOS is licensed under Apple's standard End User Licence Agreement, which is the "Terms of Use" the app links from its upgrade screen. Purchases are governed by the Apple Media Services Terms and Conditions. Where those conflict with this page on anything to do with the licence or the transaction, Apple's terms win.

Google. On Android, purchases are governed by the Google Play Terms of Service and Google's payment terms.

RevenueCat. We use RevenueCat to read your store receipt and tell the app whether Pro is active. RevenueCat is our service provider, not a party you contract with, and it never charges you — it only reports entitlement. What it receives is described in our Privacy Policy. If it were ever unavailable, the worst case is that the app cannot confirm Pro until it reaches the service again; your purchase with Apple or Google is unaffected.

We are not responsible for the availability, pricing, policies or decisions of any of them, and none of them are a party to this agreement or responsible for Primordia.

If a subscription lapses, is cancelled, or is refunded, the Pro features stop and the free tier's one-active-grow limit applies to starting a new grow.

Nothing you have already recorded is deleted, hidden or locked. Grows you started while on Pro stay fully readable and editable even if there are more of them than the free tier would let you start, harvests and photos stay where they are, and backup and restore keep working. We will not hold your own records hostage to a renewal.

Your grow records, notes and photographs are yours. We claim no ownership of them and never receive a copy — there is no Primordia server for them to reach. The only way anything leaves your device is if you export or share it yourself.

Keep your own backups of anything you cannot afford to lose. Because the records exist only on your device, a lost or wiped phone means lost records, and we have no copy to restore from.

You must be at least 13, and old enough to form a binding contract where you live. We grant you a personal, non-exclusive licence to use Primordia on devices you own or control, for your own growing — not to resell, rent out, reverse-engineer, or strip of its branding. The Primordia name, interface, illustrations and reference content belong to us or our licensors.

You can stop at any time by deleting the app; there is no account to close. If you have an active subscription, remember to cancel it in your store account — deleting the app does not cancel billing.

Species names, cultivation guidance and forecasts in the app are general information, drawn from published hobby-cultivation practice or estimated from your own logged records — never identification, food-safety or medical advice. Misidentified mushrooms can be poisonous or fatal.

Never rely on Primordia to decide whether a mushroom is safe to eat, or to identify a species. Confirm identification with a qualified expert, and consult a professional for health, dietary or regulatory decisions.

Primordia is provided as is, without warranties of any kind, to the fullest extent the law allows. Forecasts and estimates are exactly that — we do not promise they are accurate, or that the app will be uninterrupted or error-free.

To the extent permitted by law, we are not liable for indirect or consequential loss, lost profits, lost or corrupted data, failed grows, or crop loss. Where liability cannot be excluded, it is limited to the greater of what you paid us in the twelve months before the claim, or US$50. Some jurisdictions do not allow these limits, in which case they apply only as far as permitted, and your local consumer-protection rights are unaffected by anything on this page.

These terms are governed by the laws of the State of California, USA, without regard to conflict-of-laws rules, and the courts there have exclusive jurisdiction — except where your local consumer-protection law gives you the right to bring a claim at home.

We may update these terms; the effective date above changes with them, and material changes are announced in the app before they take effect. If we ever discontinue Primordia we will give reasonable notice so you can export your records first.
