Privacy Policy

Overview

StudentKit ("we," "us," or "our") operates the website studentkit.app (the "Service"). StudentKit is an individual project operated by Saisagar. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website. By using StudentKit, you agree to the collection and use of information in accordance with this policy.

StudentKit is designed with privacy as a core principle. Most tools process data entirely within your browser — nothing is sent to our servers unless explicitly stated below.

Information We Collect

We collect information in the following ways:

a) Information you provide voluntarily

• Account information: If you choose to sign in via Google (powered by Firebase Authentication), we receive your name, email address, and profile photo from your Google account. This is used solely to identify you within the app and sync your preferences.
• Contact information: If you reach out to us via email or a contact form, we collect whatever information you provide in your message.

b) Information collected automatically

• Analytics data: We use Google Analytics (tracking ID: G-X85YECWQZL) to collect anonymous usage data such as pages visited, session duration, approximate geographic location (country/city level), device type, browser type, and referring URLs. This data is aggregated and does not personally identify you.
• Advertising data: We use Google AdSense to display advertisements. Google and its advertising partners may use cookies and web beacons to serve ads based on your prior visits to this website or other websites. This enables personalized advertising (see the Cookies section below for more detail).

c) Information stored locally on your device

The following data is stored in your browser's localStorage and never transmitted to our servers:

• Streak data (daily visit tracking and streak counts)
• Learning progress and completed milestones
• Bookmarked resources and notes
• XP (experience points) events and level data
• Theme preferences and UI settings

This data remains entirely on your device. Clearing your browser data or switching devices will reset this information.

Google Analytics

We use Google Analytics (tracking ID: G-X85YECWQZL) to understand how visitors interact with our website. Google Analytics collects information such as:

• Pages visited and time spent on each page
• Your approximate geographic location (country and city level)
• Device type, operating system, and browser information
• How you arrived at our site (referral source)
• Interactions with site features and tools

This information is processed in aggregate form and does not personally identify you. Google Analytics uses cookies to distinguish unique users and sessions. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

Firebase Authentication

StudentKit offers optional sign-in via Google, powered by Firebase Authentication (a Google service). If you choose to sign in, we collect and store:

• Your display name
• Your email address
• Your profile photo URL
• A unique user identifier (UID) generated by Firebase

This data is stored securely in Firebase and is used solely to provide a personalized experience within the app. You are not required to sign in to use most features of StudentKit. You may delete your account and all associated data at any time by contacting us.

Cookie Policy

Cookies are small text files stored on your device by your web browser. We use the following types of cookies:

Most web browsers allow you to control cookies through their settings. However, disabling certain cookies may affect the functionality of the Service.

Local Processing

All calculators and productivity tools run entirely in your browser using JavaScript. Image processing tools use the HTML5 Canvas API on your device. No files are uploaded to any server. Input data you enter into tools (calculations, text, images) is never collected, stored, or transmitted by us.

No Sale of Personal Data

We do not sell, rent, trade, or otherwise transfer your personal information to third parties for monetary or other valuable consideration. We do not share your personal data with third parties for their direct marketing purposes. The only third-party data sharing that occurs is through the analytics and advertising services described above, which operate under their own privacy policies.

Data Retention

• Analytics data: Google Analytics data is retained for 14 months, after which it is automatically deleted.
• Firebase account data: Your account information is retained for as long as your account exists. You may request deletion at any time.
• localStorage data: Stored indefinitely on your device until you clear your browser data or uninstall the browser. We have no access to or control over this data.
• Advertising data: Managed by Google in accordance with Google's Privacy Policy. Ad personalization cookies typically expire within 90 days to 2 years.
• Contact inquiries: Emails and support messages are retained for up to 3 years for reference, then permanently deleted.

GDPR Compliance (European Users)

If you are located in the European Economic Area (EEA), United Kingdom, or Switzerland, you have additional rights under the General Data Protection Regulation (GDPR):

• Right of access: You may request a copy of all personal data we hold about you.
• Right to rectification: You may request that we correct any inaccurate personal data.
• Right to erasure: You may request that we delete your personal data. We will comply unless we have a legal obligation to retain it.

To exercise any of these rights, please contact us at hello@studentkit.app. We will respond to your request within 30 days. Our legal basis for processing personal data includes: legitimate interest (analytics to improve the Service), consent (personalized advertising), and contract performance (providing the Service to authenticated users).

Children's Privacy (COPPA)

StudentKit is designed for students of all ages; however, we do not knowingly collect personal information from children under the age of 13. Our Service does not specifically target children under 13 years old, and we do not require account creation to use most features. If you are a parent or guardian and believe your child under 13 has provided us with personal information, please contact us at hello@studentkit.app and we will promptly delete such information from our records.

We encourage parents and guardians to monitor their children's internet usage and to help enforce this policy by instructing their children to never provide personal information through our website without permission.

Data Security

We implement appropriate technical and organizational measures to protect your personal data against unauthorized access, alteration, disclosure, or destruction. These include:

• HTTPS encryption for all data in transit
• Firebase security rules to restrict database access
• Minimal data collection — we only gather what is necessary
• Regular review of our data practices

However, no method of transmission over the internet or electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your information, we cannot guarantee absolute security.

Third-Party Links

Our Service may contain links to third-party websites or services that are not operated by us. We have no control over, and assume no responsibility for, the content, privacy policies, or practices of any third-party sites or services. We encourage you to review the privacy policy of every site you visit.

Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or for legal, operational, or regulatory reasons. When we make material changes, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically. Your continued use of the Service after changes are posted constitutes acceptance of the revised policy.

We aim to respond to all privacy-related inquiries within 30 days.
