Privacy Policy

Duuble is a social network for profiles, hubs, posts, anonymous vote aggregates, vote receipts, comments, saved hub discussions, notifications, reports, blocks, and media uploads. This policy explains the data handled by the app and backend services.

Information We Collect

• Account and sign-in information, such as phone number, session tokens, and accepted policy versions.
• When an active member writes in a private Hub discussion, the member's verified phone number is used as the author label for other active members of that same Hub. General and other public comments use the public username instead.
• Profile information, such as username, display name, bio, profile image, and onboarding state.
• User-generated content and activity, such as posts, comments, hub details, vote receipts, anonymous aggregate vote counts, saved hub discussions, follows, memberships, reports, blocks, and uploaded media. Vote receipts show that a user voted and where the vote counted, but not the selected vote position. Aggregate vote results may be displayed from the first vote, including in Hubs with few members, so a result can be inferable when very few people have voted.
• Local contacts access is used on the device for hub invite selection and Hub readiness. We do not upload or store the full address book. The backend stores the date and time when contact access was successfully completed as a one-time Hub-readiness acknowledgement; later device-permission changes do not automatically erase that acknowledgement.
• The backend receives only phone numbers explicitly selected for a specific Hub invitation action. Under the current retention policy, those selected invitation numbers are retained without a fixed expiration period, subject to applicable account or data-deletion requests and legal, security, fraud-prevention, or abuse-investigation requirements. Hub invite SMS messages are sent from the user's device through the native SMS/share flow, not by our servers.
• Operational and security data, such as IP address, request metadata, abuse-prevention signals, reCAPTCHA results, rate-limit events, logs, and error diagnostics.
• Notification data needed to deliver in-app and push notification features.

How We Use Information

• To create and secure accounts, authenticate users, and prevent abuse.
• To operate social features, including feeds, hubs, comments, votes, follows, saved hub discussions, reports, blocks, and notifications.
• To show verified phone-number identity inside private Hub discussions and their saved previews so active members of the same Hub can identify one another.
• To store and deliver user-uploaded media through secure cloud storage.
• To investigate safety reports, enforce policies, debug services, and keep the app reliable.

Sharing

We show an active Hub discussion author's verified phone number to other active members of that same Hub, including in saved discussion previews. We do not show that phone number in General comments, public profiles, or people search. Invited or pending users, removed members, and users outside the shared Hub cannot access that private discussion identity. We also use cloud infrastructure providers and SMS delivery providers to operate the service. We do not sell personal data. We do not use collected data to track users across apps or websites owned by other companies.

User Controls

Users can update profile information, block other users, report abusive content, and request account or data deletion by contacting support. Some records may be retained when required for security, fraud prevention, legal compliance, or abuse investigations.
