Terms of Use

Last updated 11 September 2026 · End-User Licence Agreement for the Delva app and terms for getdelva.com

1. Who you are agreeing with

These terms are a legal agreement between you and Episteme Labs Ltd ("we", "us"), a company registered in England and Wales under company number 17387745, registered office 71-75 Shelton Street, Covent Garden, London WC2H 9JQ, United Kingdom, email hello@epistemelabs.co.uk. They govern the Delva app for iPhone (the "app") and, in section 14, the website at getdelva.com.

By downloading, installing or using the app you agree to these terms. If you do not agree, do not use the app. You must be at least 13 years old to use Delva; if you are under 18, you confirm a parent or guardian has agreed to these terms on your behalf and has approved any purchase.

Your use of the app is also subject to Apple's Media Services Terms and Conditions, including the Licensed Application End User Licence Agreement ("Apple's Standard EULA"). Where these terms are stricter than Apple's, these terms apply between you and us.

2. Your licence to use Delva

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the app on Apple-branded devices that you own or control, as permitted by the Usage Rules in Apple's Media Services Terms. The app is licensed, not sold; we keep all rights not expressly granted.

You may not copy, modify, reverse-engineer, decompile, extract the source code of, rent, lease, sublicense or redistribute the app or any part of it, except where the law expressly allows it despite this clause.

3. Subscriptions, prices and renewal

Delva is free to download. Full access — the complete feed, every card back and the games — requires a subscription ("Delva Premium"). Two plans are offered in the United Kingdom:

• Monthly: £7.99 per month.
• Annual: £59.99 per year (equivalent to about £5.00 a month, billed as a single payment of £59.99).

Prices include VAT. In other countries the price is shown in local currency on the in-app purchase screen before you confirm; the App Store price at the time of purchase is the price you pay.

How billing works. Payment is taken by Apple from the payment method on your Apple Account when you confirm the purchase. Your subscription renews automatically for the same period at the then-current price unless you cancel at least 24 hours before the end of the current period. Apple charges the renewal within 24 hours before the current period ends. You can see the renewal date and price at any time in Settings → your name → Subscriptions.

Price changes. If we raise the price of a plan, Apple will notify you in advance and, where the law or Apple's rules require it, ask for your consent before the new price applies. If you do nothing and consent is required, your subscription will lapse rather than renew at the higher price.

Renewal reminders. Apple sends email reminders before each renewal of an annual subscription. We will also remind you inside the app.

4. Cancelling and refunds

Cancelling. You can cancel at any time and without giving a reason: open Settings on your iPhone, tap your name, tap Subscriptions, choose Delva and tap Cancel Subscription. Cancelling stops the next renewal; you keep full access until the end of the period you have already paid for. Deleting the app does not cancel the subscription.

Refunds. Because Apple takes payment, Apple handles refunds. Request one at reportaproblem.apple.com; Apple decides in line with its own policies and the law. We cannot issue App Store refunds ourselves, but if Apple declines and you believe you are entitled to one under UK consumer law, email us and we will do what we can.

Your 14-day right to cancel. Under the Consumer Contracts Regulations 2013 you normally have 14 days from purchase to change your mind about digital content. When you buy through the App Store you are asked to agree that supply starts immediately and to acknowledge that you lose this right once it does; that is why cancelling a subscription normally takes effect at the end of the paid period rather than instantly. Nothing in this section limits your right to a refund where the app is faulty (see section 11).

5. Free trials and offers

We may offer free trials or introductory prices. [CONFIRM: if a trial exists, state its length here, e.g. "A free trial lasts 7 days. Unless you cancel at least 24 hours before it ends, your subscription starts automatically at the price shown when you began the trial."] Any unused part of a free trial is forfeited when you buy a subscription. Offers are one per Apple Account unless we say otherwise.

6. The content

Delva's cards are written from public sources — chiefly Wikipedia and Wikidata — with the help of automated tools, then checked against those sources. We aim for accuracy, but history is contested and sources contain errors. Delva is for general interest and learning, not professional advice, and it should not be relied on as the sole source for academic work, legal, medical, financial or safety decisions. If you find a mistake, tell us and we will correct it.

Some topics concern war, atrocity, disease and death. We write about them in a register that fits their weight, but we do not add content warnings to individual cards. If you find a subject distressing, swipe on.

Text from Wikipedia is available under the Creative Commons Attribution-ShareAlike 4.0 licence; our cards adapt it and, where they reproduce Wikipedia text substantially, that text remains under the same licence. Images are used under their respective licences, which are noted where the image appears or available on request.

7. Acceptable use

You agree not to:

• use the app in any way that breaks the law or these terms;
• scrape, harvest or bulk-download cards, or use bots or automated tools against the app or our servers;
• interfere with, overload or attempt to gain unauthorised access to the app, our servers or other users' data;
• remove or alter any copyright notice, or pass off Delva content as your own;
• share your subscription in breach of Apple's rules (Family Sharing, where we enable it, is fine).

8. Intellectual property

The Delva name, logo, app, website, design, software and original content are owned by Episteme Labs Ltd or our licensors and are protected by copyright, trade mark and other laws. You may use the content for your own personal, non-commercial learning. Any feedback or suggestions you send us may be used without obligation to you.

9. Changes to the app and these terms

We update the app often. We may add, change or remove features and content, and we may need to stop providing the app altogether. If we make a change that materially reduces what a paid subscription gives you, we will tell you in advance so you can cancel before the next renewal. We may also update these terms; the date at the top shows the current version and we will notify you in the app of significant changes. Continuing to use the app after a change means you accept it.

10. Ending the agreement

You can end this agreement at any time by cancelling any subscription and deleting the app. We may suspend or end your access if you seriously or repeatedly breach these terms, giving you notice and a chance to put things right where that is reasonable. If we end your access for a reason other than your breach while you have an active subscription, you can ask Apple for a pro-rata refund of the unused period. Sections 6, 8, 11, 12, 13 and 15 survive termination.

11. What we promise, and what we don't

If you are a consumer in the United Kingdom, the Consumer Rights Act 2015 says digital content must be of satisfactory quality, fit for purpose and as described, and gives you the right to repair, replacement or a price reduction if it is not. Nothing in these terms affects those rights. Consumers elsewhere keep whatever mandatory protections their own law gives them.

Beyond those legal rights, the app and content are provided "as is". We do not promise that the app will be uninterrupted, error-free or compatible with every device, or that every historical statement is complete or correct.

12. Our liability

We do not exclude or limit our liability where it would be unlawful to do so — including for death or personal injury caused by our negligence, for fraud, or for breach of your consumer rights. Otherwise, we are not liable for losses that were not foreseeable when you started using the app, losses caused by your breach of these terms, or business losses, since Delva is for personal use. Our total liability to you for all other claims in any 12-month period is limited to the amount you paid for the app in that period.

13. Terms required by Apple

Because the app is distributed through Apple's App Store, Apple requires the following:

1. Acknowledgement. This agreement is between you and Episteme Labs Ltd only, not Apple. Apple is not responsible for the app or its content. We, not Apple, are solely responsible for the app.
2. Scope of licence. The licence in section 2 is limited to a non-transferable licence to use the app on Apple-branded products that you own or control, as permitted by the Usage Rules in Apple's Media Services Terms, except that the app may be accessed and used by other accounts associated with you via Family Sharing or volume purchasing.
3. Maintenance and support. We are solely responsible for providing any maintenance and support for the app. Apple has no obligation to furnish any maintenance or support services.
4. Warranty. We are solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the app fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price of the app to you; to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the app, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to a warranty are our sole responsibility.
5. Product claims. We, not Apple, are responsible for addressing any claims by you or any third party relating to the app or your possession or use of it, including product-liability claims, claims that the app fails to conform to any legal or regulatory requirement, and claims arising under consumer-protection, privacy or similar legislation.
6. Intellectual property claims. If a third party claims that the app or your use of it infringes their intellectual-property rights, we, not Apple, are solely responsible for the investigation, defence, settlement and discharge of that claim.
7. Legal compliance. You represent and warrant that you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
8. Developer contact. Episteme Labs Ltd, 71-75 Shelton Street, Covent Garden, London WC2H 9JQ, United Kingdom; hello@epistemelabs.co.uk.
9. Third-party terms. You must comply with any applicable third-party terms when using the app (for example, your mobile-data agreement).
10. Third-party beneficiary. Apple and Apple's subsidiaries are third-party beneficiaries of this agreement and, upon your acceptance of it, will have the right (and will be deemed to have accepted the right) to enforce it against you as a third-party beneficiary.

14. Using the website

getdelva.com is provided for information about Delva. You may browse it and link to it. You may not scrape it, frame it, or use its content commercially without permission. Links to other sites are provided for convenience; we are not responsible for their content. The website's privacy practices are described in our Privacy Policy.

15. Law, disputes and contact

These terms are governed by the law of England and Wales. If you are a consumer living elsewhere in the United Kingdom, the European Union, or another country, you also benefit from any mandatory protections of the law where you live, and you may bring proceedings in your local courts as well as in England and Wales. We will always try to resolve a problem informally first — email hello@epistemelabs.co.uk and a founder will reply, usually within a day. EU consumers may also use the European Commission's online dispute-resolution platform.

If any part of these terms is found unenforceable, the rest still applies. Our failure to enforce a term is not a waiver of it. You may not transfer this agreement to anyone else; we may transfer it to a company that takes over Delva, provided your rights are not reduced.
