Privacy Policy
Last updated: September 2026
Grumble collects the minimum information necessary to provide the service:
We do not collect: name, email, phone number, location, IP address (beyond standard server logs), or any identifying information.
We never sell, rent, or share your data with third parties for advertising or marketing purposes.
Rants that receive 5 or more reports are automatically hidden from the public feed. This is done to maintain a safe community environment. Reported content is reviewed and may be permanently removed.
Your rant content is shared publicly in the community feed. No personally identifiable information is ever attached to your posts. Other users see only your rant text, category, and reactions — never your identity.
Your rants are stored on our servers until you delete them. You can delete your own rants at any time within the app. For data deletion requests, contact us with your device ID (accessible from the app settings).
Grumble is not directed at children under 13. Due to the nature of user-generated content, the app is intended for users aged 17 and above. We do not knowingly collect information from children under 13.
We use HTTPS encryption for all data transmission. Server infrastructure is secured with industry-standard practices. No payment information is collected or stored.
We may update this privacy policy from time to time. Changes will be reflected by the "Last updated" date above. Continued use of the app constitutes acceptance of the updated policy.
This app displays ads served through Unity LevelPlay, an ad mediation platform operated by Unity Technologies (formerly ironSource). To deliver and measure ads and to prevent fraud, the Unity LevelPlay SDK and the ad networks it works with may collect device information such as the advertising identifier (Google Advertising ID), IP address, device model, operating system version, language setting, and your interactions with ads. This information is processed by Unity and its ad network partners under their own privacy policies: Unity Privacy Policy. You can reset your advertising ID or opt out of personalized ads at any time in your device settings (Settings > Google > Ads).
