COOKIE POLICY
Last updated: October 5, 2026
1. INTRODUCTION AND SCOPE
This Cookie Policy explains how Telecom Apps LLC and its affiliate Stape Online Ltd, each doing business as Kleos (together, "Kleos," "we," "us," or "our"), use cookies and similar technologies on our website at https://kleos.io and our platform at https://app.kleos.io (together, the "Services"). Our full company details are set out in Section 1 of our Privacy Policy.
This Cookie Policy supplements our Privacy Policy, available at https://kleos.io/privacy, which describes how we collect, use, and protect personal information more generally. Capitalized terms used but not defined in this Cookie Policy have the meanings given to them in the Privacy Policy. In the event of any conflict between this Cookie Policy and the Privacy Policy regarding cookies and similar technologies, this Cookie Policy governs.
Certain subdomains and services operated on our behalf by third parties (for example, our careers site at careers.kleos.io, operated by Teamtailor) present their own cookie notices and consent tools, which govern cookies set on those subdomains.
2. WHAT ARE COOKIES AND SIMILAR TECHNOLOGIES?
Cookies are small text files that are stored on your browser or device when you visit a website. Cookies set by us are called "first-party cookies"; cookies set by parties other than us are called "third-party cookies." We also use similar technologies, such as pixels, tags, software development kits (SDKs), and local storage, which function in a comparable way. In this Cookie Policy, we refer to all of these technologies together as "cookies."
Cookies may be "session" cookies, which expire when you close your browser, or "persistent" cookies, which remain on your device for a set period or until you delete them.
3. CATEGORIES OF COOKIES WE USE
Consistent with Section 8 of our Privacy Policy, we use the following categories of cookies:
Essential Cookies. These cookies are necessary for the operation, security, and functionality of the Services. They enable core features such as authentication, security, network management, and user preferences (including storing your cookie consent choices). Because these cookies are strictly necessary to provide the Services, they cannot be disabled through our cookie preference center.
Analytics Cookies. These cookies help us understand how visitors use our website and Services, including which pages are visited, how users navigate the Services, and whether errors or technical issues occur. We use this information to monitor performance, improve functionality, and enhance the user experience. Analytics cookies are used only with your consent where required by applicable law.
Advertising Cookies. These cookies help us and our advertising partners understand your interests and interactions so that we can measure the effectiveness of our marketing campaigns and, where applicable, display advertisements that are more relevant to you across websites and online services. Advertising cookies are used only with your consent where required by applicable law.
4. COOKIES USED ON THE SERVICES
The table below lists the cookies and similar technologies currently used on the Services. We update this table from time to time as the cookies we use change.

Reactions feature: local-storage token and browser fingerprint | Kleos | Essential | Recognize your browser so that a reaction you leave on website content is counted only once. The fingerprint is calculated in your browser from technical device characteristics using an open-source library, is used solely for this purpose, is not combined with other data, and is not shared with third parties. | Until you clear your browser storage. The fingerprint is recalculated on each visit and is not stored as a cookie. |

Audience measurement cookies | Third-party analytics provider | Analytics | Distinguish visitors and measure how our website is used (pages viewed, navigation paths, errors) so that we can improve it. | 2 years |
Campaign attribution items (local storage and session storage) | Kleos | Analytics | Remember the campaign parameters from the link you used to reach our website so that a demo request can be attributed to the right campaign. | Local storage: until you clear your browser storage. Session storage: until you close your browser. |
Advertising conversion cookie | Third-party advertising provider | Advertising | Measures whether a visit resulting from one of our online advertising campaigns led to a demo request or another conversion. | 3 months |
A tag management tool is used to load the analytics and advertising technologies listed above; it does not itself set cookies. Analytics and advertising cookies are used only with your consent where consent is required by applicable law. Items described as local storage or session storage are stored in your browser rather than as cookies and are treated as cookies for the purposes of this Cookie Policy. The names of the specific cookies and of the providers currently in use, which may change from time to time, are available on request at support@kleos.io.
5. LEGAL BASIS AND CONSENT
Where required by applicable law (including in the European Economic Area and the United Kingdom), we will obtain your consent before placing or accessing any cookies that are not strictly necessary for the operation of the Services. Essential cookies are used on the basis of our legitimate interests in operating, securing, and providing the Services, and, where applicable, as strictly necessary to provide a service you have requested.
You may accept or reject optional cookies through our cookie preference center when you first visit our website, and you may update your preferences at any time through the cookie settings available on our website.
6. HOW TO MANAGE COOKIES
You can manage your cookie preferences in the following ways:
Cookie preference center. Use the cookie settings available on our website to accept or reject analytics and advertising cookies at any time.
Browser settings. Most browsers allow you to refuse or delete cookies through their settings. If you disable essential cookies, parts of the Services may not function properly.
Opt-out preference signals. We honor browser-based opt-out preference signals, such as Global Privacy Control (GPC), as a valid request to opt out of the sale or sharing of personal information for the browser or device that sends the signal, to the extent required by applicable law.
Third-party opt-outs. Some third parties provide their own opt-out mechanisms, such as the Google Ads Settings page and the opt-out tools offered by the Digital Advertising Alliance (optout.aboutads.info) and the Network Advertising Initiative (optout.networkadvertising.org).
7. THIRD-PARTY COOKIES
Some cookies on the Services are set by third-party providers, such as analytics, advertising, customer-communications, scheduling, security, and consent-management providers. These providers may process the information collected by their cookies in accordance with their own privacy notices. We do not control third-party cookies; the table in Section 4 identifies the type of provider for each cookie, the identity of the providers currently in use is available on request at support@kleos.io, and we encourage you to review the applicable provider’s privacy notice.
8. U.S. STATE PRIVACY RIGHTS
Where the use of cookies for analytics or advertising purposes is considered a "sale" or "sharing" of personal information under applicable U.S. state privacy laws, you may exercise your opt-out rights through our cookie preference center or through an opt-out preference signal as described in Section 6. Further information about your rights, and how to exercise them, is set out in Section 12 of our Privacy Policy.
9. CHANGES TO THIS COOKIE POLICY
We may update this Cookie Policy from time to time, including to reflect changes in the cookies we use. The "Last updated" date at the top of this Cookie Policy reflects the most recent revision. We encourage you to review this Cookie Policy periodically.
