Privacy Policy

This Policy covers personal data processed by Core Sync Zero (operated by GUBENDRAN RAJ KUMAR) as a service provider to account holders and as a website operator for visitors and leads.

When a gym, shop, or other business customer stores information about their members or customers in our products, that business is typically the data controller for that information, and we process it on their instructions to provide the product.

Account and profile data: name, email, phone, business name, login credentials, and plan or role details.

Billing and transaction data: subscription plan, invoices, payment status, and related tax details. Card or UPI details are typically handled by payment processors; we receive confirmation and limited payment metadata.

Product data you enter: gym member and attendance records; shop products, inventory, customers, and sales; Word Vault saved words, notes, and learning progress.

Usage and device data: approximate location derived from IP, browser/app type, pages viewed, feature usage, crash logs, and cookies or similar technologies on our marketing sites.

Support and contact data: messages you send through contact forms, email, or in-product support.

Provide, maintain, and improve the Services; authenticate users; and deliver features you request.

Process trials, subscriptions, invoices, and customer support.

Send service notices (security, billing, material product changes). Marketing messages are sent only where permitted and you can opt out of non-essential marketing.

Monitor reliability and security, prevent fraud and abuse, and comply with legal obligations.

Analyse aggregated or de-identified trends to improve products.

Gym management: member personal details, attendance, and payment history are stored so gym operators can run their business. Operators should only collect what they need and handle it lawfully.

Billing: shop customer and sale records support POS and reporting. Product databases are separate from the gym app unless we clearly offer a shared feature.

Word Vault: learning activity and saved vocabulary help personalise your study experience. Avoid storing sensitive personal data in notes fields.

We do not sell personal data.

We share data with service providers who help us host, store, send email, process payments, monitor uptime, or analyse product usage — under contracts that limit use to providing services to us.

We may disclose information if required by law, regulation, legal process, or to protect rights, safety, and security.

If we undergo a merger, acquisition, or asset transfer, personal data may be transferred as part of that transaction with appropriate notice where required.

We retain account and Customer Data while your account is active and for a reasonable period afterward for backups, dispute resolution, fraud prevention, and legal compliance.

You may request deletion of your account data where the product supports it, subject to legal retention needs. Business customers remain responsible for exporting data they need before account closure.

We use administrative, technical, and organisational measures designed to protect personal data, such as encrypted transport (HTTPS), access controls, and restricted production access.

No method of transmission or storage is fully secure. Please use strong passwords and protect account access.

Our marketing and product sites may use cookies or local storage for essential functions (for example language preference), analytics, and improving site performance.

You can control cookies through browser settings. Disabling some cookies may affect site features.

Depending on applicable law (including India’s Digital Personal Data Protection Act framework as it applies), you may have rights to access, correct, update, or request deletion of personal data we hold about you, and to withdraw consent where processing is consent-based.

If your data was submitted by a gym or shop using our products, please contact that business first for access or correction requests. We will assist account holders as needed to respond.

To exercise rights regarding your Core Sync Zero account or website inquiries, contact us using the details below.

Our business products are intended for adults and organisations. Word Vault may be used by students, but we do not knowingly collect personal data from children under 13 without appropriate parental or guardian involvement where required by law.

If you believe we have collected such data inappropriately, contact us and we will take reasonable steps to delete it.

We primarily serve users in India. Infrastructure or processors may process data in other countries. Where we transfer personal data, we take steps intended to provide appropriate safeguards consistent with applicable law.

We may update this Privacy Policy from time to time. The “Last updated” date will change when we do. Continued use of the Services after an update means you acknowledge the revised Policy.

For material changes, we will provide reasonable notice on the website, in-product, or by email where appropriate.
