CookiePolicy
How we use cookies and similar technologies, and how you can change your preferences at any time.
Date of publication: May 02 2026
This Cookie Policy describes the cookies and similar technologies used by SENTX LABS, SL (CIF B16403198, registered office at C/ Ortega y Gasset 9, 6th & 7th floor, 30009 Murcia, Spain) on the SentX platform (the “Service”). It is published in compliance with Article 5(3) of Directive 2002/58/EC (the ePrivacy Directive) as transposed into Spanish law by Article 22(2) of Law 34/2002 (LSSI-CE), and complements our Privacy Policy.
1. What are cookies?
Cookies are small text files stored on your device by your browser when you visit a website. The Service also uses similar technologies such as localStorage, sessionStorage, IndexedDB, pixels, and SDK identifiers. Throughout this policy, “cookies” refers to all such technologies unless otherwise specified.
2. Categories of cookies we use
Strictly necessary (always on, no consent required)
These are required for the Service to function: authentication state, wallet connection state, CSRF protection, security rate-limiting, language preference, and the cookie consent record itself. They are loaded on first visit and cannot be disabled in the consent banner because the Service cannot operate without them.
| Identifier | Provider | Purpose | Duration |
|---|---|---|---|
sentx-cookie-consent | SentX (first-party) | Stores your cookie preferences so we never re-prompt you. | Persistent until you click “Reset cookie preferences” |
wc@2:* (localStorage) | WalletConnect | Wallet session persistence between page loads. | Persistent (cleared on disconnect) |
WALLET_CONNECT_V2_INDEXED_DB | WalletConnect | Encrypted wallet pairing data. | Persistent (cleared on disconnect) |
| Auth token (memory + Redis-backed) | SentX (first-party) | Server-side session, bound to wallet. | Server-side; rotates with login |
| Sentry error-tracking client state (localStorage / IndexedDB) | Sentry (Functional Software, Inc.) | Operational security & reliability monitoring — captures unhandled errors, performance traces, and release metadata so SentX can diagnose and fix faults that affect users. Treated as strictly necessary; not session replay (which is listed under Analytics). | Session-scoped |
Analytics (consent required)
Help us understand how the Service is used so we can find bugs and improve features.
| Identifier | Provider | Purpose | Duration |
|---|---|---|---|
_ga, _gid, _gat, _gtm_* | Google Tag Manager / Google Analytics | Page view, session and engagement metrics. | Up to 2 years |
_clck, _clsk, CLID, ANONCHK, MR, MUID, SM | Microsoft Clarity | Heatmaps, behavioural metrics, session replay. | Up to 1 year |
| Sentry session-replay sampling cookies | Sentry | Reproduce error sessions for debugging (text masked, media blocked). | Session-scoped |
Functional (consent required)
Enable optional features beyond strictly-necessary functionality.
| Identifier | Provider | Purpose | Duration |
|---|---|---|---|
| HelpScout Beacon cookies | Help Scout | Support chat widget — conversation state and identity. | Up to 1 year |
Marketing
SentX does not currently set marketing or advertising cookies. Should we introduce any in the future, this Cookie Policy will be updated and your consent will be requested via the cookie banner before any such cookie is set.
3. How to manage your preferences
You can change your cookie preferences at any time by clicking the button below. This will reopen the consent banner and reset your stored preferences.
You can also disable or delete cookies through your browser settings. Note that disabling strictly-necessary cookies may break authentication or wallet connection.
4. International transfers
Several analytics and functional providers (Google, Microsoft Clarity, Sentry, HelpScout) may process cookie-derived data in the United States. SentX relies on the EU-U.S. Data Privacy Framework adequacy decision and/or the European Commission's Standard Contractual Clauses for these transfers, as detailed in our Privacy Policy.
5. Updates to this Cookie Policy
We may update this Cookie Policy when our cookie use changes. When we add cookies in a new category that requires your consent, the consent banner will be presented again. The date at the top of this page reflects the most recent update.
