Who we are
Critto is made by Nexferra LTD, registered in England and Wales. Company number: 16605957. Registered office: 3rd Floor, 86-90 Paul Street, London, EC2A 4NE, United Kingdom. In these terms, “we” means Nexferra LTD. Contact help@critto.app.
Adults and accounts
You must be 18 or older. Give accurate account details, keep your sign-in safe and tell us if someone uses your account without permission. You are responsible for what you ask your crittos to do.
Your little AIs
You can create crittos, chat, use memory and voice, and ask them to work in the Den. They are AI, not people. They can make mistakes. Check important answers and actions. They do not provide professional medical, legal or financial advice.
If a message suggests suicide or self-harm, Critto may show crisis support and encourage you to contact a person. Checks can miss things. Critto is not an emergency service. In immediate danger, call your local emergency number (999 in the UK, 112 in the EU, 911 in the US). Samaritans: 116 123 in the UK and Ireland. US: call or text 988.
Your AI subscriptions
You may connect ChatGPT, Claude, Grok, Meta Muse or Antigravity. We use the account on your behalf. You are responsible for its subscription, limits and terms, and for checking that your use is allowed. Read the Antigravity warning before connecting. The provider's privacy settings apply.
Critto Smarts is included in every plan within its monthly fair-use allowance. Allowances and available models are shown in the app. We may limit abuse or stop requests when an allowance is used up; purchased Critto Smarts packs can cover extra AI and voice use.
The Den
The Den is your cloud computer. Safety checks may block an action or ask you first; they cannot guarantee that every action is safe. Only grant access you want your crittos to have. No illegal, abusive or harmful activity, attacks on others, crypto-mining or spam. We can suspend Den access to prevent harm or investigate misuse.
Your content and shared cards
You keep your rights in what you provide and make, subject to other people's rights and AI providers' terms. You give us permission to store, process and display it as needed to run Critto. You must have the rights to what you upload or share. Shared cards are public; other people can adopt a copy. Your chats, private memories and keys are not included. Removing a card does not remove copies already adopted.
Plans, billing and refunds
Standard and Pro have the limits and prices shown before you buy. New customers get one card-backed seven-day Standard trial, which converts to the monthly plan unless cancelled. Polar is the merchant of record: it sells the plan, collects payment and handles tax and receipts. Paid plans renew monthly until cancelled. Cancel any time through the app's billing portal; access normally continues to the end of the paid period. Standard and Pro include unlimited Den use; the server meters it internally for cost and capacity. Monthly Critto Smarts and voice allowances reset as shown in the app and do not roll over. Purchased Critto Smarts packs cover extra Critto Smarts and voice use and never expire. Refunds remove the corresponding purchased balance.
UK and EU consumers normally have 14 days from concluding the contract to withdraw. Email help@critto.app or contact Polar to request withdrawal or a refund. If you expressly ask for a service to start during that period, you may owe a proportionate amount for the service supplied. A withdrawal right for digital content is lost only if supply begins with your prior express consent, your acknowledgement of that loss and the required confirmation. Fully performed services lose the right only where the legal conditions are met. Agreeing to these terms alone does not waive that right. Your statutory rights for faulty or misdescribed services remain.
When a paid plan ends, the Den is kept for 90 days before deletion, with reminders. Chats and memories stay. If you downgrade, crittos beyond the new plan's limit nap rather than being deleted.
Self-hosting and privacy
Self-hosted software is provided as-is, subject to its software licence and rights that cannot be excluded. You run, secure, update and back up your own server, and pay your providers. Our hosted-service privacy notice does not cover data kept on your own server. Please don't share sensitive information, such as health, beliefs or your sex life. We don't aim to collect it. If you share it anyway, it is used to answer you in that chat and is not saved to memory unless you ask. Crisis support checks are the one safety exception. You can delete the chat or memory note, or your account. See our privacy notice for details and our privacy notice for the hosted service.
Changes, suspension and leaving
We will tell you before important changes to these terms or the service take effect. If you disagree, you can cancel and export your data. We may suspend or end access for serious misuse, legal requirements or security threats, and explain why where lawful. You can delete your account in Settings, with a 7-day grace period, or contact us. We will honour refund rights and offer a reasonable chance to export data where lawful and safe.
Responsibility and law
We use reasonable care and skill. Nothing excludes or limits liability for death or personal injury caused by negligence, fraud, or anything English law does not allow us to exclude. We are responsible for reasonably foreseeable loss caused by our breach. We are not responsible for loss that was not foreseeable or business losses from consumer use. These terms do not reduce mandatory consumer rights.
The law of England and Wales governs these terms. Consumers keep the mandatory protections of the country where they live and may bring claims in courts permitted by those protections. Contact help@critto.app about any problem.
