1. Introduction
Welcome to Poststack™ ("we," "our," or "us"). These Terms of Service ("Terms") govern your use of our social media scheduling & analytics platform (poststack.ai, app.poststack.ai) and digital marketing agency directory, including our website at https://poststack.ai, our scheduling application at https://app.poststack.ai, and all related services, features, and content (collectively, the "Service").
Trademark Notice: Poststack™ is a trademark. All rights reserved. Unauthorized use of this trademark is strictly prohibited.
By accessing or using the Service, you agree to be bound by these Terms. If you disagree with any part of these Terms, you may not access the Service.
Defined terms. In these Terms, "Data Fiduciary" means Poststack.ai, the entity that, alone or jointly with others, determines the purpose and means of processing personal data under the Digital Personal Data Protection Act, 2023 ("DPDP"). "Data Principal" means you, the individual to whom the personal data relates. "Personal data" has the meaning given in DPDP. These terms have the same meaning in our Privacy Policy.
2. Acceptance of Terms
By accessing and using Poststack™, you accept and agree to be bound by the terms and provision of this agreement.
These Terms apply to all users of the Service, including without limitation users who are browsers, agencies, contributors of content, and users of our social media scheduling service.
Age requirement (18+). The Service is intended for business and professional use by individuals aged 18 and above. If you are under 18, you may not use the Service. By using the Service, you represent and warrant that you are at least 18 years old.
Date of birth at signup. To verify your age, we collect your date of birth at signup and block registration if the date indicates you are under 18. Your date of birth is used only for this age verification purpose, as described in our Privacy Policy.
Consent by use (DPDP Section 6). To the extent that any use of the Service involves processing of your personal data on the basis of consent under DPDP Section 6, your continued use of the Service after being presented with the relevant notice constitutes your consent to that processing, in addition to any explicit consent you give through our consent prompts (for example, the cookie banner, marketing email opt-in, and OAuth authorisations for social media platforms). You may withdraw consent at any time as described in our Privacy Policy; withdrawal does not affect the lawfulness of processing carried out before withdrawal.

Your privacy is important to us. Our Privacy Policy governs our collection, use, storage, transfer, and protection of your personal data, and forms part of these Terms. By using the Service, you consent to the processing of your personal data as described in the Privacy Policy.
Purpose limitation (DPDP Section 8(1))
We process your personal data only for the specific purposes listed in our Privacy Policy. We do not process your personal data for any purpose that is not stated in the Privacy Policy, and we do not use broad or unspecified purposes such as "platform improvement and analytics" as a catch-all basis. If we intend to use your personal data for a new purpose, we will update the Privacy Policy and obtain your consent for that new purpose before processing begins.
Your rights as a Data Principal
Your rights under DPDP Sections 11 to 14 — access, correction and erasure, grievance redressal, and nomination — and the instructions for exercising them, are described in our Privacy Policy. To exercise any of these rights, follow the instructions in the Privacy Policy or write to [email protected].
Your duties as a Data Principal (DPDP Section 15)
As a Data Principal, you agree to the duties set out in DPDP Section 15:
- not to register yourself with a false identity or impersonate another person;
- not to suppress, where suppression would mislead us, any material information about yourself when providing personal data for processing;
- not to provide false information to us;
- not to impersonate another person or entity when using the Service.
A breach of these duties may result in suspension or termination of your account under Section 14 of these Terms, in addition to any consequences under applicable law.
Grievance redressal (DPDP Section 13, Rule 14)
Our Grievance Officer is reachable at [email protected]. We acknowledge complaints within 24 hours and respond fully within 90 days, in line with DPDP Rule 14(3). If you are not satisfied with our response, you may file a complaint with the Data Protection Board of India; the Board complaint portal is linked in our Privacy Policy.
DPDP compliance undertaking
Poststack undertakes to comply with the DPDP Act 2023 and the DPDP Rules 2025 in its processing of your personal data, including the obligations on notice, consent, security safeguards, breach notification, retention, and Data Principal rights. These Terms and our Privacy Policy are to be interpreted in line with DPDP, and any conflict between these Terms and DPDP will be resolved in favour of compliance with DPDP to the extent permitted by law.
GDPR and CCPA
If you are an EU/EEA resident or a California resident, the GDPR or CCPA sections of our Privacy Policy apply to you in addition to DPDP. These frameworks are addressed as secondary in our Privacy Policy because the Service is India-focused but receives global visitors.
