1. Introduction
Welcome to Sisteren. Sisteren is a social community and marketplace designed to help sisters connect, communicate, share content, and buy, sell, exchange, or give away items with other members. This Privacy Policy explains how Sisteren collects, uses, stores, and protects information when you create an account or use our website and services.
2. Information We Collect
When you create an account or use Sisteren, we may collect information you provide, including your name, username, email address, profile information, profile photo, interests, location information you choose to provide, posts, photos, marketplace listings, and other content you submit. We may also collect technical information such as your IP address, browser type, device information, and information about how you use Sisteren.
3. How We Use Your Information
We may use your information to create and manage your account, provide community and marketplace features, display your profile and content according to your privacy settings, enable communication between members, improve Sisteren, protect the security of the platform, prevent misuse or fraud, respond to support requests, and comply with applicable legal requirements.
4. Profile and Community Content
Sisteren allows members to create profiles and share content with other members. Information you choose to include in your profile, posts, photos, comments, and other community activity may be visible to other users depending on the privacy settings and features available on Sisteren. Please avoid posting sensitive personal information that you do not want others to see.
5. Marketplace Listings
Sisteren allows members to post items to sell, buy, exchange, or give away. Information included in a marketplace listing, such as item descriptions, photos, prices, and information the seller chooses to provide, may be visible to other users. Transactions and arrangements are made directly between members unless Sisteren specifically states otherwise. Members should use care when sharing personal information or arranging an exchange with another member.
6. Private Messages
Sisteren may provide private messaging features that allow members to communicate with one another. Messages are intended for the participating members; however, information may be accessed or processed when reasonably necessary to operate the service, investigate reports of abuse or safety concerns, protect users, maintain security, or comply with legal obligations.
7. Cookies and Similar Technologies
Sisteren may use cookies and similar technologies to keep members logged in, remember preferences, provide website functionality, improve performance, maintain security, and understand how the website is used. Some third-party services or plugins used by Sisteren may also set cookies when their features are used.
8. How We Share Information
Sisteren does not sell your personal information. We may share information with service providers that help us operate, secure, maintain, or improve the website. Information may also be disclosed when required by law, to protect the rights and safety of Sisteren or its members, or to investigate suspected fraud, abuse, or violations of our policies.
9. Children and Teen Users
Sisteren is intended for users age 13 and older. We recognize that younger members require additional privacy and safety considerations. Users under 18 should avoid publicly sharing sensitive personal information such as their home address, telephone number, school location, or other information that could compromise their safety. Sisteren may provide additional privacy or safety protections for minor accounts.
10. Date Security
Sisteren uses reasonable administrative and technical measures designed to protect personal information from unauthorized access, loss, misuse, or disclosure. However, no website, online service, or method of electronic transmission can guarantee complete security. Members are responsible for keeping their passwords confidential and should notify Sisteren if they believe their account has been accessed without permission.
11. Your Privacy Choices
Members may be able to update their profile information, adjust available privacy settings, and control certain information displayed to other members. You may also contact Sisteren to ask questions about your personal information or request changes or deletion where applicable. Some information may need to be retained when required by law, for security purposes, or to resolve disputes.
12. Third-Party Services
Sisteren may use third-party services, plugins, hosting providers, email services, analytics tools, or other technologies to operate and improve the website. These third parties may process limited information as necessary to provide their services and may have their own privacy policies governing their practices.
13. Changes to This Privacy Policy
Sisteren may update this Privacy Policy as the website, community, marketplace features, or legal requirements change. When changes are made, the “Last Updated” date at the top of this page may be revised. We encourage members to review this Privacy Policy periodically.
14. Account Deletion
Members may request deletion of their Sisteren account and associated personal information, subject to information that Sisteren may need to retain for legal, security, fraud-prevention, or dispute-resolution purposes. Some content shared with other members may remain where removal is not technically possible or where retention is legally permitted.
