Cookie Policy
Last Updated: December 1, 2025
1. Introduction
This Cookie Policy explains how Welltory Inc. ("Welltory", "we", "us", or "our") uses cookies and similar tracking technologies on www.welltory.com, app.welltory.com, and other related pages (collectively, the "Service"). These technologies help us provide, improve, and protect our Service while enhancing your user experience.
Some of the purposes for which these technologies are used may require your consent. Whenever consent is given, it can be freely withdrawn at any time following the instructions provided in this document.
This policy should be read in conjunction with our Privacy Policy, which provides additional information about how we collect, use, and protect your personal data.
2. What Are Cookies and Similar Technologies
Cookies are small text files placed on your device when you visit our website. They are widely used to make websites work efficiently and provide information to website owners.
For simplicity, we use the term "Trackers" in this policy to refer to all technologies that allow us to access and store information or use resources on your device. These include:
- Cookies (browser-based text files)
- Web beacons and pixel tags
- Local storage objects
- Software Development Kits (SDKs)
- Other similar tracking technologies
Note: While cookies work on both web and mobile browsers, we use the term "Cookies" specifically for browser-based trackers. In mobile app contexts, we refer to other appropriate technologies like SDKs.
We use both first-party Trackers (managed directly by us) and third-party Trackers (enabling services provided by external providers). Unless otherwise specified, third-party providers may access the Trackers they manage.
The lifespan of these Trackers varies: some expire when you close your browser (session cookies), while others persist for longer periods as specified in the tables below. For more detailed information about specific Trackers, including their exact durations and additional technical details, you may consult the privacy/cookie policies of the respective third-party providers or contact us.
