The Osmium Browser itself, in its base form, does not collect, transmit, or store any of the following:
There are no built-in telemetry systems, no usage tracking, and no connections made to Osmium Developments servers in the course of normal browser operation. Osmium is yours and only yours from the moment you open it.
If you choose to create an Osmium Account in order to publically publish to the Addon Store or other account-based features, we collect the following:
We do not collect your real name, date of birth, phone number, payment details, or physical address unless explicitly required for a specific feature (such as paid addons), in which case you will be clearly informed before providing that information.
We do not sell, rent, or share your account information with third parties for marketing or advertising purposes under any circumstances.
When you use the Osmium Addon Store:
Addons installed through the Osmium Addon Store may have access to browser functionality depending on the permissions they declare. Osmium's permission system requires every addon to declare what it can access before you install it.
We review addons for policy compliance before they are listed in the Store, but we cannot guarantee the privacy practices of every addon developer. You should review the privacy policy of any addon before installing it, particularly for addons that request permissions such as "network", "history", or "tabs".
We are not responsible for data collected by Osmium addons.
We are not responsible for any damage, data loss, privacy violations, or security incidents caused by third-party addons.
Websites you visit through Osmium may collect their own data, use cookies, and employ tracking technologies. This data collection is governed by each website's own privacy policy, not ours. Osmium does not intercept, modify, or report on your interactions with third-party websites.
You can use privacy-focused addons such as ad blockers, tracker blockers, or cookie managers — available in the Osmium Addon Store — to limit third-party tracking while browsing.
Osmium stores certain data locally on your device to support browser functionality. This includes:
This data stays on your device. It is not transmitted to us or any third party by Osmium itself.
Osmium does not include a built-in default search engine. Search engine support is provided through addons. If you install a search engine addon, your search queries may betransmitted directly to that search engine's servers. Osmium does not intercept or log your search queries. Any search engines are in accordince to their own privacy policies, and Osmium is not responsible for their actions.

Osmium is not directed at children under the age of 13. We do not knowingly collect unnecessary information from children under 13. If you believe a child under 13 has provided us with personal information, please contact us and we will delete it promptly.
We take reasonable technical and organizational measures to protect information held in connection with Osmium Accounts and Store services. This includes encrypted storage of passwords (bcrypt hashing), HTTPS for all web services, and rate limiting to prevent abuse.
No system is perfectly secure. We cannot guarantee absolute security, and you use Osmium's account-based features at your own risk.
Depending on your location, you may have rights regarding your personal data including:
To exercise any of these rights, contact us at [email protected]. We will respond within a reasonable time frame and in accordance with applicable law.

If changes materially affect how we handle your data, we will make reasonable efforts to notify you through the Osmium website or direct communication via email.
