Databuddy provides cookieless collection and controls for the information you send. This page describes those controls and their limits. See the Privacy Policy and Data Processing Agreement for our data-protection commitments.

Privacy-First Design

The browser tracker uses first-party localStorage for visitor information and sessionStorage for sessions. Session IDs use a 30-minute reuse window; a continuously open page can keep its current session longer.

Standard analytics event records omit raw IP addresses after request handling and approximate country, region, and city lookup. By default, ingestion hashes visitor IDs with a rotating daily salt. Your website's anonymizeVisitorIds setting can disable that transformation or apply it according to the visitor's country.

The identify API links activity to profile IDs and traits you supply. Profile IDs are separate from visitor-ID anonymization. Page paths, titles, custom properties, and errors can also contain personal information; review those payloads before sending them.

Privacy Controls

Enable the features you need using the SDK configuration. For example, this configuration disables errors, outgoing-link events, and performance collection:

import { Databuddy } from "@databuddy/sdk/react";

<Databuddy
  clientId="YOUR_WEBSITE_ID"
  trackWebVitals={false}
  trackOutgoingLinks={false}
  trackErrors={false}
/>;

This is a collection example, not a consent configuration. Where prior consent is required, delay mounting the component or loading the script until consent is granted.

Local Data Storage and Opt-Out

The browser tracker honors Global Privacy Control, Do Not Track, and the stored opt-out preference. Its built-in helpers are:

window.databuddyOptOut();
window.databuddyOptIn();

Opting out stops tracking, clears local tracker identifiers, and stores the preference when localStorage is available. Opting in does not override GPC or DNT. These helpers do not delete information already collected on the server.

Data Deletion in Practice

Visitors should contact the website owner about collected information. We assist customers with access, correction, and deletion requests; contact privacy@databuddy.cc. Hashing an identifier or leaving identification disabled does not guarantee that no personal data was collected.

Access Control Settings

Collection requires an active website ID. Origin filtering is an ingestion control, not proof of domain ownership: a non-browser client can supply an Origin header.

Open your website's Settings → Security to configure additional allowed origins and IP restrictions.

Allowed Origins

When a request includes an Origin, the registered hostname and its subdomains are accepted by default. Additional allowed origins broaden that set; they cannot exclude the registered domain.

Without a configured list, requests lacking an Origin are accepted. With a nonempty list, a missing or unrecognized Origin produces a 403 response.

Supported entries include:

example.com: the hostname.
*.example.com: the apex and its subdomains.
localhost: local development.
*: any parseable origin.

Matching uses the hostname, not a particular scheme or port. The origin check does not itself enforce HTTPS.

Allowed IP Addresses

An empty list imposes no IP restriction. A configured list accepts only requests with a trusted matching IP address; other requests receive a 403 response.

Supported entries include individual IPv4 or IPv6 addresses and IPv4 CIDR ranges, such as 192.0.2.10 or 192.0.2.0/24.

This path uses the trusted cf-connecting-ip header. It does not fall back to arbitrary x-forwarded-for or x-real-ip values. With SELFHOST=true, configured IP allowlists reject requests rather than trusting potentially spoofed proxy headers.

Test restrictions with the actual clients and infrastructure that will send events. Blocking legitimate sources prevents their data from being collected.

Data Protection

Requests are validated, size-limited, and rate-limited. Profile display names and email addresses use AES-256-GCM field encryption when the server key is configured; production ingestion requires that key. Arbitrary event properties and profile traits are outside this field-encryption mechanism.

Infrastructure, AI, billing, and delivery services process information needed for the features you enable. See the Data Policy for their roles.

Privacy Compliance

Cookieless collection does not automatically remove consent requirements. Review browser storage, the information collected, and applicable rules. See the web analytics privacy guide.

Implementation Security

Content Security Policy

Allow the tracker CDN in script-src and the configured ingestion endpoint in connect-src. For the default hosted endpoints, those are https://cdn.databuddy.cc and https://basket.databuddy.cc. Merge these into your existing policy; do not replace your application's other restrictions.
