Without an account
No personal data is collected. Your favorites, your positions, your language and your acceptance of the warnings stay in your browser and are never sent to the server. The site uses no advertising cookies and no audience-measurement tools, and its fonts are hosted on the site itself.
With an account
We process your email address (sign-in) and the state of your subscription (status, renewal date, Stripe customer ID). The Jytalis account is shared across Jytalis services. Payment data is processed directly by Stripe; we never have access to your card number.
Notifications
If you turn on notifications, we store the technical delivery address provided by your browser, its encryption keys, the list of your favorite cryptos and your language, solely to send you notifications. This data is deleted when you turn notifications off on the device, or when the browser reports that the subscription is no longer valid.
Custom alerts (Pro)
If you create alerts, we store for each one the crypto, the threshold type, its value and when it was triggered, solely to notify you. You can delete them at any time; they are also erased with “Delete my Crypto data”. Your positions (“My positions”) are stored only on your device.
Service providers
Supabase (accounts and notifications), Stripe (payment), Netlify (site hosting and technical logs). These providers may process data outside the European Union, notably in the United States; these transfers are covered by the European Commission's standard contractual clauses or by the EU–US Data Privacy Framework.
Retention
Account data: until the account is deleted. Billing data: the legal accounting retention period.
Your rights
Access, rectification, erasure, objection and portability: write to azus111@yahoo.fr. You can also contact the CNIL (cnil.fr), the French data protection authority, or the data protection authority of your country.
What we never collect
Neither your wealth, nor your income, nor the contents of your crypto wallet.
