The legal entity operating NisiHub is responsible for determining the purposes and means of processing personal data.
Depending on the services used, personal data may include:
Account information: Name, username, email address, telephone number, and profile details.
Authentication data: Account identifiers, verification information, session data, and security-related information.
Listings: Titles, descriptions, prices, photographs, locations, categories, and contact details.
Messages: Communications exchanged through available platform messaging features.
Location: Selected island, city, area, and any more precise location voluntarily supplied or permitted through a device.
Technical data: IP addresses, browser and device details, technical identifiers, diagnostic records, and usage information.
Support information: Messages, complaints, and requests submitted to NisiHub.
Personal data may be processed to:
Create and maintain accounts.
Authenticate users and protect account security.
Publish and manage classified advertisements.
Enable communication between users.
Display listings based on location and category.
Respond to support requests and reports.
Detect fraud and prevent misuse.
Fulfil legal obligations.
Improve platform performance and, where legally permitted, analyze usage.
The applicable legal basis depends on the particular activity and may include contractual necessity, legal obligations, legitimate interests, or consent when required.
Each purpose and legal basis must reflect the service's actual processing operations.
NisiHub uses Google's Firebase services for certain authentication and notification functions.
Where phone verification is enabled, Firebase Authentication may process telephone numbers, IP addresses, device details, and information needed to prevent abuse.
Phone verification confirms control of a telephone number during the authentication process. It does not independently establish a user's legal identity.
Further details are available in Google's Firebase privacy documentation: https://firebase.google.com/support/privacy
Information voluntarily published in advertisements may be visible to other users, visitors, and search engines.
This may include photographs, descriptions, selected location details, public profile information, and contact details, depending on privacy settings and available platform features.
Users should avoid sharing sensitive information or the personal data of third parties without an appropriate legal basis.
Removing information from NisiHub may not immediately remove copies indexed or stored by independent third-party services.
Where platform messaging is available, relevant communication data may be processed to operate the service, maintain security, investigate reports, and comply with legal requirements.
Users should not share passwords, verification codes, or sensitive financial information in conversations.
NisiHub uses selected location information to present island-based and local classified advertisements.
More precise device location may be processed where the user chooses to grant the relevant permission and the feature is enabled.
Users may control location access through their browser or device settings.
Essential cookies or similar technologies may be used to provide account sessions, security features, language preferences, and other necessary functions.
Optional analytics, advertising, or personalization technologies require appropriate transparency and consent where applicable.
Any use of Google Analytics or other analytics services must correspond to the tools actually deployed.
Non-essential tracking technologies must not be activated before any consent required by law has been obtained.
NisiHub may send service-related messages concerning account access, verification, listing activity, and platform communications.
Where enabled, Firebase Cloud Messaging may support push notifications.
Marketing notifications will be subject to applicable consent and user preference requirements.
NisiHub may use service providers for website hosting, email delivery, identity verification, notifications, maps, analytics, technical support, and security.
These may include Google Firebase and relevant hosting or infrastructure providers.
Service providers must be engaged under appropriate contractual and legal arrangements. Information should not be disclosed for unrelated purposes without a valid legal basis.
Some service providers may process information outside the European Economic Area.
Where personal data is transferred internationally, the applicable GDPR safeguards must be assessed and implemented, including relevant adequacy decisions or contractual safeguards.
The actual transfer locations and mechanisms must be verified against the services in use.
Personal data is retained only as long as necessary for the applicable purpose or as required by law.
Retention may differ for user accounts, listings, messages, authentication records, technical logs, and support requests.
Specific retention periods or deletion criteria must be finalized after confirming the actual technical configuration and legal requirements.
NisiHub aims to apply technical and organizational measures appropriate to the risks associated with processing personal data.
No online service can guarantee absolute security.
