Welcome. These terms are the agreement between you and me about your use of the Codex mobile application. By installing or using Codex, you agree to them. If you don't, please uninstall the app.
Codex is built and operated by Marouane, an individual based in Garches, Île-de-France, France. I am a solo developer. There is no company, no team, no investors — just me. For any question about these terms, email licane.apps@gmail.com.
Codex is a mobile application that presents mental frameworks as collectible card decks. You read cards, optionally write reflections, and track your progress. Some content is free; some is available only with a Codex Pro subscription.
Codex is provided "as is." I do my best to keep it working, but I make no specific promises about uptime, accuracy of content, or that the app will be free of bugs or interruptions. The frameworks presented are summaries of published ideas, simplified for accessibility. They are not professional advice — not medical, legal, financial, psychological, or otherwise. Use your own judgment.
You can use Codex anonymously without creating an account. If you create one, you agree to:
You can delete your account at any time from inside the app (Settings → Delete account) or by emailing me. Deletion is permanent and removes your data per the Privacy Policy.
You may use Codex for your own personal, non-commercial purposes. You may write reflections, save cards, track progress, and build your own reading journey. That's the entire intended use.
You may not:
If you do any of these, I may suspend or terminate your account without warning.
The reflections you write inside Codex are yours. I do not claim ownership of them, do not sell them, do not use them to train AI models, and do not share them with anyone.
To run the app, I need a limited license to store your reflections on my server (when you have an account) so they can sync across your devices and appear back to you. That license ends when you delete your reflection or your account.
You are responsible for the content of your reflections. If you write something illegal or that violates someone else's rights, that's on you. I may remove content I believe violates these terms or the law.
The card decks, prompts, illustrations, copy, code, and design of Codex are protected by copyright. They are mine, used under license, or in the public domain. The frameworks themselves (Cipolla's laws, Cialdini's principles, etc.) are ideas published by their original authors — those ideas are not mine, but my specific presentation of them in card form is.
You get a personal license to use the app and its content while your account is active. You don't get the right to redistribute it.
Codex Pro is a recurring subscription. Pricing is shown to you before purchase. Subscriptions auto-renew unless you cancel at least 24 hours before the renewal date.
You cancel through Google Play or the Apple App Store, not through me. Until you cancel, you keep getting charged.
Two subscription options are available:
Different users may see different offers based on their engagement with the app. The price you see at purchase is the price you pay. Once you subscribe at a given price, that price stays in effect at renewal until I change it (with notice — see "Price changes" below).
Payment is processed by Google Play on Android and the Apple App Store on iOS, not by me. Their billing terms apply alongside these. I never see your card details.
Under EU consumer law you normally have 14 days to withdraw from a digital service purchase and get a full refund. By starting to use Codex Pro immediately after purchase, you expressly waive this right, as permitted by Article L. 221-28 of the French Code de la Consommation. This waiver is presented to you at the purchase screen.
If you didn't waive it and haven't started using paid features, you can request a refund within 14 days by emailing me.
Outside the EU withdrawal right, refunds are at my discretion. As a general rule:
For technical reasons, refunds for purchases made through Google Play and the App Store sometimes have to be processed by them directly. If I can't refund you, I'll point you to the right place.
I can change subscription prices at any time. If a price change affects a subscription you've already paid for, the new price will apply at the next renewal — not retroactively. I'll notify you by email at least 30 days before the change takes effect. You can cancel before the renewal if the new price doesn't work for you.
Some Codex content is free for everyone. Some content requires Codex Pro. I reserve the right to move content between the free and Pro tiers — for example, opening a previously-Pro deck to free users, or moving a free deck to Pro after launch. This won't affect existing Pro subscribers (you keep access to everything you had access to when you subscribed) but may affect future free users.
I can suspend or terminate your account if you violate these terms, if you abuse the app or other users, or if your continued use exposes me or other users to legal risk. If I do, you lose access immediately, and I may not refund unused subscription time when the termination is for cause.
You can stop using Codex any time. Delete the app, or delete your account, or both.
I can also discontinue Codex entirely. If I do, I'll give at least 30 days' notice by email to active users with accounts, refund the unused portion of any active subscriptions on a pro-rata basis, and provide a way to export your reflections before the shutdown.
Codex is provided "as is" without warranties of any kind, to the maximum extent permitted by law. I don't guarantee that the app will be uninterrupted, error-free, or that any specific outcome will result from using it.
To the maximum extent permitted by applicable law, my total liability to you for any claim related to Codex is limited to the amount you paid me in the 12 months before the claim arose, or €50, whichever is greater.
Some EU consumer rights cannot be waived. Nothing in these terms limits or excludes my liability for gross negligence, fraud, or willful misconduct. If you're an EU consumer, your statutory rights remain in full effect regardless of what these terms say.
If your use of Codex (especially uploaded content or violations of these terms) causes me to be sued or face a claim from a third party, you agree to cover my reasonable legal costs to defend against that claim. This doesn't apply to claims arising from my own actions or breach of these terms.
These terms are governed by French law. Any dispute will be heard by the competent courts of Nanterre, France, unless you're an EU consumer, in which case you may also bring the dispute before the courts of the EU country where you live, as guaranteed by Article 18 of the Brussels I Regulation.
Before going to court, we agree to try to resolve things by email first. Most disputes have honest fixes — refunds, account restoration, content corrections — that don't need a courtroom.
EU consumers can also use the European Commission's Online Dispute Resolution platform.
I can update these terms. Material changes (changes that meaningfully reduce your rights or add obligations) will be announced inside the app and by email if I have your email. The "Last updated" date at the top changes whenever the terms do. Continued use after a change means you accept the new terms. If you don't accept them, stop using Codex — and if you have an active subscription, you can cancel and request a pro-rata refund for the unused period.
