Cardira · Gearoenix Ltd
Terms of Use
Effective 1 August 2026 · Applies to Cardira for Android and iOS
The short version. Cardira is free. You may use it on your own devices for as long as you like. It shows ads. You can leave a tip if you want to, but a tip is a thank-you and unlocks nothing — everyone gets exactly the same app.
Cardira opens other people's dictionary websites. Those sites are theirs, not ours; we do not control what is on them and we are not connected with them.
Nothing here takes away the rights you have as a consumer under UK law.
1. Who we are, and these terms
Cardira is published by Gearoenix Ltd, a company registered in England and Wales, company number 17239319, registered office Flat 18 37 Wellington Road, London, England, E6 2DD (“we”, “us”, “our”).
These terms are the agreement between you and us for your use of the Cardira app. By installing or using Cardira you accept them. If you do not accept them, do not use the app — you can remove it at any time.
These terms are written in English and, together with our Privacy Policy, are the whole agreement about the app between you and us. Your purchase of anything through an app store is also subject to that store's own terms, which are between you and the store.
2. Your licence to use Cardira
We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use Cardira on any device you own or control, for your own personal, non-commercial use, in accordance with these terms and the usage rules of the app store you obtained it from.
We do not sell you the app; we license it to you. All intellectual property rights in Cardira — the software, the name, the design, the icons and other artwork we created, and the curated dictionary catalogue — remain ours or our licensors'.
The licence lasts until it is ended under section 14.
3. What you may not do
Except to the extent the law says you may despite this clause, you must not:
- copy, sell, rent, sub-licence, distribute or otherwise commercially exploit the app;
- reverse engineer, decompile or disassemble the app, or attempt to derive its source code;
- remove or obscure any advertising, any “Ad” label, any copyright notice or the non-affiliation notice in section 5;
- interfere with the app's advertising or purchasing functions, or generate artificial ad impressions, clicks or rewards;
- use the app to break the law, to infringe anyone's rights, or in breach of any dictionary website's own terms of use.
4. Your words are yours
Everything you put into Cardira — your words, your progress, the dictionaries you add — stays on your device. We claim no rights over it, we do not receive it, and we cannot see it. See the Privacy Policy for the detail.
Because there is no server, your device holds the only copy. You are responsible for keeping backups: use the Export function in Settings, and keep your device's own backup enabled. We are not liable for data you lose by uninstalling the app, resetting or losing a device, or clearing the app's storage. In-app tips and the local supporter badge do not survive reinstalling the app; that is explained in section 8.
5. Third-party dictionaries
Cardira is an independent app. It is not affiliated with, endorsed by, or sponsored by any of the dictionaries it links to. All product names, logos and brands are the property of their respective owners.
Cardira's purpose is to open a word's page on a dictionary website of your choosing, in a browser tab. It does not copy, cache, reformat or store any dictionary's content.
Those websites are operated by other people. We provide the links “as is”, as an ordinary web link. In particular:
- we do not control, check, endorse or take responsibility for any content, definition, translation, advertisement or other material on a linked site;
- we do not promise that any linked site will remain available, keep the same web address, be free of charge, or continue to hold an entry for a given word;
- when you open a linked site you are subject to its terms and privacy policy, not ours;
- if a site changes its address structure, links from Cardira to that site may stop working until we ship an update. That is not a defect we can prevent.
If you add your own dictionary by pasting a web address, you are responsible for that address and for complying with the target site's terms.
Cardira is a study aid for revisiting words you have chosen. It is not itself a dictionary, and it does not warrant the accuracy of anything a dictionary says.
6. Brands, icons and takedown
Each dictionary is shown by its unmodified icon at icon size, together with its plain-text name, solely so you can tell which site a word will open in. This is referential use, and it is not a claim of any connection with the brand owner. We ship no artwork derived from, generated from or restyled from anyone else's icon, logo or wordmark.
If you own a brand shown in the app and want its icon removed, email cardira-privacy@gearoenix.com and we will remove it within five working days of receiving your request. No formal notice is required. Removing an icon does not mean we accept any allegation; we would simply rather comply than argue.
If you believe anything in Cardira infringes your copyright or trade mark, contact us at the same address with enough detail to identify the material and your right in it.
7. Advertising
Cardira is free and carries advertising. Ads appear as clearly labelled cards in your word list, and as short videos you can choose to watch to support us. No ad is ever forced on you: the optional video ads only load after you tap to accept, and declining them changes nothing about how the app works.
Ads are supplied by Google and by advertising partners we have activated; the advertiser, not us, is responsible for the content of an ad and for anything you buy from one. We ask Google to cap ad content at the “general audiences” rating and require the same of every partner we activate, but we cannot review individual creatives in advance. If you see an ad in Cardira that you think breaches that rating, please tell us at cardira-privacy@gearoenix.com with a screenshot and we will report it.
Watching an ad is not a purchase and costs you nothing but your time. It grants you no feature and no entitlement — only a cosmetic thank-you recorded on your own device.
8. Tips
Cardira offers a small number of fixed-price tips: a voluntary way to support the work if you want to. Please read this section before buying one.
- A tip unlocks nothing. It removes no ads, grants no feature, gives you no learning advantage and confers no entitlement of any kind. Everyone uses the same app whether they tip or not. The only thing you receive is a thank-you message and a cosmetic supporter badge shown on your own device.
- Tips are consumable. They can be bought again, and, once bought, they are used up. Because a consumable purchase cannot be restored under either store's rules, your supporter badge does not survive reinstalling the app or moving to a new device, and there is nothing to restore. We know that is a rough edge; we accept it rather than run a server that would hold your data.
- These are tips to a business, not charitable donations. Gearoenix Ltd is a for-profit company. No part of a tip goes to a charity, and no tax receipt is issued.
- The store takes the payment. Tips are sold through Apple's or Google's billing system, which is the merchant of record for the transaction. We never see your payment details. Prices, taxes and currency conversion are set and applied by the store.
- We do not offer refunds ourselves, and we have no technical ability to issue one: we do not hold the payment. A refund request must go to the store — Apple or Google Play — and is decided under that store's policy. This does not affect the statutory rights described in sections 9 and 10.
- Do not tip if you cannot afford it. If you are under 18, only make a purchase with the permission of the person who owns the payment method.
9. Your cancellation rights
If you are a consumer in the United Kingdom, the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 normally give you 14 days to cancel a contract made at a distance. Similar rights apply in the EEA.
A tip is digital content that is supplied to you immediately and in full at the moment you confirm the purchase. So, at the point of purchase:
You expressly consent to the tip being supplied immediately, and you acknowledge that by doing so you lose your right to cancel under regulation 37 of those Regulations once supply has begun.
You are shown that statement in the app and you confirm it by completing the purchase. If, for any reason, you were not asked for that consent and acknowledgement before the purchase completed, then you keep the 14-day cancellation right and you bear no cost for the tip — tell us at cardira-privacy@gearoenix.com and we will make sure the purchase is unwound.
Where the store, rather than us, is the seller of the tip, the cancellation right is exercised against the store using the links in section 8. We will help if you cannot get an answer from them.
10. Your other consumer rights
Nothing in these terms excludes or limits your rights under the Consumer Rights Act 2015 or any other law that cannot be excluded. In particular, digital content supplied to you must be of satisfactory quality, fit for a purpose you made known, and as described; if it is not, you may be entitled to a repair, a replacement, a price reduction or a refund.
Free-to-use software is still covered where you paid nothing, to the extent the Act applies. For general guidance on your rights, contact the Citizens Advice consumer service at citizensadvice.org.uk/consumer.
11. Availability, updates and changes
Cardira runs on your device and works offline for its core purpose; opening a dictionary and showing ads require a connection. We do not promise the app will be available without interruption or free of every error.
We may issue updates that fix problems, add or remove features, refresh the dictionary catalogue, or keep the app working with new versions of Android and iOS. Depending on your settings, updates may install automatically. If you do not install an update, parts of the app may stop working over time — most obviously, dictionary links whose sites have changed.
We may change these terms — for example, if the law changes or the app changes. We will update the effective date at the top of this page and, where a change materially reduces your rights, we will bring it to your attention in the app before it takes effect. Continuing to use Cardira after a change means you accept it; if you do not, uninstall the app.
We may stop publishing Cardira, or withdraw it from a particular country or store, at any time. If we do, the app already on your device will keep working for as long as your operating system supports it, and you should export your words.
12. Disclaimers
Except for the statutory rights described in sections 9 and 10, and to the fullest extent the law allows, Cardira is provided “as is” and we give no warranties, conditions or other terms of any kind, whether express or implied, including as to merchantability, fitness for a particular purpose or non-infringement.
In particular we do not warrant that:
- using Cardira will cause you to learn anything, or produce any particular result — spaced repetition is a technique, not a guarantee;
- any dictionary entry reached through the app is accurate, complete or current;
- any link will keep working, or any dictionary will remain available;
- the app is free of every defect, or that defects will be corrected.
13. Our liability
We do not exclude or limit our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, for breach of your statutory rights as a consumer, or for anything else that cannot lawfully be excluded.
Subject to that, and because Cardira is supplied free of charge apart from voluntary tips:
- we are not liable for loss or corruption of your data, for loss of profit, revenue, business, opportunity or goodwill, or for any indirect or consequential loss;
- we are not liable for anything on, or arising from, a third-party website you open through the app, or for any transaction between you and an advertiser;
- we are liable only for loss or damage you suffer that is a foreseeable result of our breaking these terms or failing to use reasonable care and skill;
- our total liability to you for all claims connected with Cardira is limited to the greater of the total amount you have paid us through the app in the 12 months before the claim, and £0.01.
You use Cardira for personal purposes. If you use it for any business purpose we have no liability to you for loss of profit, business, business interruption or business opportunity.
14. Ending this agreement
You may end this agreement at any time by deleting the app. We may end it if you materially break these terms, in which case you must stop using Cardira and delete it. Sections 4, 12, 13, 16 and 17 survive.
15. Additional terms for the Apple App Store
If you obtained Cardira from the Apple App Store, the following apply and prevail over anything inconsistent above:
- These terms are between you and Gearoenix Ltd only, not with Apple. Apple is not responsible for Cardira or its content.
- Your licence is limited to using Cardira on any Apple-branded device you own or control, as permitted by the App Store Usage Rules, except that it may also be accessed by other accounts associated with you via Family Sharing or volume purchasing.
- Apple has no obligation to provide any maintenance or support for Cardira.
- If Cardira fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price (if any). To the maximum extent permitted by law, Apple has no other warranty obligation and any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform to a warranty are our responsibility.
- We, not Apple, are responsible for addressing any claim by you or a third party relating to Cardira or your use of it, including product liability claims, any claim that it fails to conform to a legal or regulatory requirement, and claims under consumer protection, privacy or similar legislation.
- We, not Apple, are responsible for the investigation, defence, settlement and discharge of any third-party claim that Cardira or your use of it infringes that third party's intellectual property rights.
- You represent that you are not located in a country subject to a US Government embargo or designated as a “terrorist supporting” country, and that you are not on any US Government list of prohibited or restricted parties.
- You must comply with any applicable third-party terms when using Cardira.
- Apple and its subsidiaries are third-party beneficiaries of these terms and, upon your acceptance, will have the right to enforce them against you.
- Our contact details for questions, complaints or claims are in section 18.
16. General
If any part of these terms is found to be unlawful or unenforceable, the rest continues to apply. If we do not insist that you do something you are required to do, or delay in taking steps against you, that does not mean we have given up any right.
You may not transfer your rights under these terms to anyone else. We may transfer ours to another company, and we will tell you in the app if that happens; your rights will not be reduced by it.
Apart from Apple's rights in section 15, nobody other than you and us has any right to enforce these terms under the Contracts (Rights of Third Parties) Act 1999.
17. Governing law and jurisdiction
These terms and any dispute arising out of them are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction.
If you are a consumer resident elsewhere in the United Kingdom, you may also bring proceedings in the courts of your own part of the UK, and the mandatory consumer-protection law of that part applies. If you are a consumer resident outside the United Kingdom, nothing in this section deprives you of the protection of the mandatory laws of your country of residence, or of your right to bring proceedings in the courts there.
