At Calculi-TN (accessible via calculi.tn), your privacy is important to us. This Privacy Policy explains what information we collect, how we use it, when we share it, and the choices and rights you have regarding your personal data. This policy is intended to reflect applicable privacy requirements, including the Tunisian Organic Law No. 2004-63, and where applicable the GDPR and CPRA.

1. Information We Collect

We may collect the following categories of information when you use our website or services:

Account information: name, email address, password hash, and other registration details.
Academic information: education level, bac section, grades, subjects, averages, and related calculation inputs.
Contact information: email address, phone number, and any other contact details you provide.
Location information: city, region, or country, where you choose to provide it or where it is reasonably inferred from your interaction.
Usage data: pages viewed, feature usage, device information, browser type, IP address, and approximate location derived from IP.
Communication data: messages, feedback, support requests, and responses you send to us.
Consent preferences: your preferences regarding analytics, cookies, marketing, and partner sharing.

We may also collect anonymized or aggregated data that does not directly identify you. Where data can reasonably identify you, we treat it as personal data.

2. How We Use Your Information

We use personal data for the following purposes:

To provide calculators, predictions, and related educational tools.
To create and manage user accounts.
To save your calculations, preferences, and history where this feature is enabled.
To improve, maintain, and secure our website and services.
To analyze site usage and measure performance.
To communicate with you about your account, support requests, service updates, and policy changes.
To display relevant university or partner offers where you have opted in.
To comply with legal obligations, enforce our terms, and prevent fraud or abuse.

3. Cookies, Analytics, and Tracking

We use cookies and similar technologies to operate the site, remember preferences, analyze traffic, and support advertising. We may use Google Analytics and other analytics tools to understand how users interact with the website.

For advertising, we may use Google AdSense, Ezoic, or similar partners. These services may use cookies, pixels, and related technologies to deliver, measure, and improve ads, including personalized ads where permitted and enabled.

You can manage cookies through your browser settings and, where available, through our on-site consent controls.

4. Third-Party Advertising

We may show advertisements from third-party advertising partners. These partners may collect or receive information from this website and elsewhere on the internet to support ad delivery and measurement, subject to their own policies and your applicable consent choices.

5. University and Partner Sharing

We do not sell raw personal data by default. We may share your personal data with universities, education providers, or other partners only in the following cases:

With your explicit opt-in consent: if you check a consent box or otherwise clearly authorize us to share your data with universities or partners.
To provide a requested service: for example, when you ask us to connect you with an institution or request contact from a university.
With service providers: for hosting, analytics, email delivery, security, or other operational support, under confidentiality obligations.

When you opt in, the data shared may include your name, contact details, bac section, grade or average, subject information, preferences, and other information you submit for matching or admission guidance. We may also send a lead identifier and timestamp so that partner universities can verify origin and delivery.

You can withdraw your consent for future partner sharing at any time by changing your account settings or contacting us. Withdrawal does not affect sharing that already occurred before the withdrawal.

6. No Sale of Personal Information Without Consent

We do not sell your personal information for money or other valuable consideration unless we have a lawful basis to do so and, where required, your explicit consent. If we introduce any feature that could be interpreted as a sale or exchange of personal information under applicable law, we will disclose that clearly and provide the appropriate opt-out or consent mechanism.

7. Data Retention

We retain personal data only for as long as needed for the purposes described in this policy, unless a longer retention period is required by law, contract, or legitimate operational needs. We may retain anonymized or aggregated data indefinitely because it no longer identifies you directly.

8. Data Security

We use reasonable technical and organizational measures to protect personal data against unauthorized access, disclosure, alteration, loss, or destruction. No method of transmission or storage is fully secure, and we cannot guarantee absolute security.

9. Your Rights

Depending on your location and applicable law, you may have the right to access, correct, delete, restrict, object to, or port your personal data. You may also have the right to withdraw consent where processing is based on consent.
