Terms of Service

Core Sync Zero is a sole proprietorship owned and operated by GUBENDRAN RAJ KUMAR. It provides software products for Indian businesses and learners, including gym management, shop billing (POS), and Word Vault vocabulary tools. References to “we”, “us”, or “Core Sync Zero” mean GUBENDRAN RAJ KUMAR operating as Core Sync Zero.

These Terms apply to all Core Sync Zero products unless a product-specific addendum says otherwise.

Gym management: tools for memberships, attendance, payments, trainers, and related gym operations.

Billing: shop POS features such as products, inventory, customers, sales, and related reporting, including browser and desktop use where offered.

Word Vault: vocabulary learning features such as lookup, saving words, review, and progress tracking.

We may improve, add, or remove features over time. Material changes that reduce core paid functionality will be communicated reasonably in advance when practicable.

You must provide accurate account information and keep login credentials confidential. You are responsible for activity under your account.

If you use the Services on behalf of a business, you confirm you have authority to bind that business to these Terms.

You must be legally able to enter a contract in India (or your place of residence) to use paid or business features.

Some products offer free trials or free plans. Trial length, limits, and conversion to paid plans are described at signup or on the product pricing pages.

Paid plans are billed according to the plan you select. Prices shown on marketing pages typically exclude GST unless stated otherwise. Applicable taxes may be added to invoices.

Unless required by law or stated otherwise at purchase, fees are non-refundable once a billing period has started. You may cancel renewal to stop future charges.

We may suspend or limit access if payment fails and remains unresolved after reasonable notice.

You agree not to misuse the Services. That includes attempting to break security, scrape or overload systems without permission, reverse engineer except where allowed by law, or use the Services for unlawful, deceptive, or harmful activity.

You must not upload malware, infringing content, or content you do not have rights to process. You must not use the Services to harass others or violate privacy or data-protection laws.

We may investigate suspected abuse and suspend or terminate accounts that violate these Terms.

You retain ownership of data you submit to the Services (“Customer Data”), such as gym member records, shop customer and sale records, or Word Vault learning data you create.

You grant us a limited licence to host, process, and display Customer Data only as needed to provide and improve the Services, prevent abuse, and comply with law.

You are responsible for having a lawful basis to collect and process personal data you enter into the Services (for example, gym members or shop customers). You should inform those individuals as required by applicable law.

We do not claim ownership of your Customer Data. Product databases are separate unless we expressly say data is shared across products.

The Services, including software, branding, design, and documentation, are owned by Core Sync Zero or its licensors. These Terms do not transfer ownership to you.

You may use the Services only as permitted under your plan. You may not copy, resell, or redistribute the Services except as we expressly allow.

The Services may integrate with third-party tools (for example payment providers, hosting, analytics, or messaging). Those services are governed by their own terms and privacy policies.

We are not responsible for third-party outages or policies outside our reasonable control, but we will take commercially reasonable steps to keep core integrations reliable.

The Services are provided on an “as is” and “as available” basis to the maximum extent permitted by law. We do not warrant uninterrupted or error-free operation.

You are responsible for backing up important Customer Data where the product offers export or backup options, and for verifying that outputs (such as invoices or reports) meet your business and compliance needs.

To the maximum extent permitted by applicable law, Core Sync Zero will not be liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, revenue, goodwill, or data.

Our aggregate liability arising out of or relating to the Services in any twelve-month period is limited to the fees you paid us for the affected product in that period (or, if you are on a free plan, INR 1,000).

Nothing in these Terms excludes liability that cannot be limited under Indian law.

You may stop using the Services at any time and may delete or close your account where the product provides that option.

We may suspend or terminate access if you materially breach these Terms, fail to pay fees when due, or create risk to the Services or other users.

After termination, we may delete or anonymise Customer Data according to our retention practices and Privacy Policy, except where we must retain information for legal or security reasons.

We may update these Terms from time to time. The “Last updated” date at the top will change when we do. Continued use of the Services after updates become effective constitutes acceptance of the revised Terms.

If a change is material, we will provide reasonable notice through the website, product, or email where appropriate.

These Terms are governed by the laws of India. Courts in India shall have exclusive jurisdiction over disputes arising from these Terms, subject to any mandatory consumer protections that apply to you.
