Privacy Policy

Here we explain what data KESÉV uses, what for, who it is shared with and what control you have over it.

What data we collect

Only what is needed to calculate your Secure Salary and keep your history:

  • Your email, to create your access and notify you about your account.
  • What you log: amount, merchant, category and date of each expense or income, and your goals.
  • The voice notes and receipt photos you send to log an expense (see “Artificial intelligence” below).
  • Your initial diagnostic answers, such as your approximate income.
  • Basic app usage data, to fix errors and improve the service.

KESÉV does not connect to your bank or ask for your banking passwords.

What we use it for

To read your voice notes and photos, calculate your Secure Salary and simulated financial fund, show your history, manage your subscription, protect against abuse and improve the service. We do not sell your personal data or use it for third-party advertising.

Artificial intelligence and international transfer

When you log by voice note or photo, that file is sent to our artificial intelligence provider (Google, through the Gemini API) only to extract the amount, merchant and category. KESÉV does not store the audio or the photo on its servers: it only stores the result you confirm.

This processing may take place on servers outside your country. The provider handles the data under its own terms. AI can make mistakes, which is why you confirm every expense before saving it. More detail in the AI Notice.

Services we use to operate

These are the services we use and what each one is for:

  • Supabase: database and access to your account.
  • Vercel: hosting for the app and this page.
  • Resend: sending sign-in emails and notices.
  • Hotmart: subscription billing. KESÉV does not receive or store your card details.
  • Google (Gemini API): reading voice notes and photos with artificial intelligence.

We do not share your data with anyone else, unless a competent authority requires it by law.

Your rights

You can ask to access your data, correct it, export it or have it deleted entirely, and object to certain uses. When you delete your account, your history and goals are erased. Write to workingkesev@gmail.com from your account email and we will reply.

Retention, security and minimum age

We keep your data while you have an active account. We protect your information with per-user restricted access, encrypted connections and database security rules; even so, no system is 100% foolproof.

KESÉV is only for people aged 18 or older.

Changes to this policy

If we change something important, we will update the date above and email you before it applies. If the language versions differ, the Spanish version prevails.
