Core Privacy Principle: Qenlo is a local-first, embedded vector database engine. The core engine and its SDKs run entirely on your local machine or host environment. They make zero automated outbound network requests, collect no telemetry by default, and transmit no vector data or search queries to any remote server.

1. Data Controller Identification

This website and the Qenlo open-source project are maintained by Akshat Singh Kushwaha (operating under the organization moniker a3ro-dev). For any inquiries, concerns, or requests regarding this Privacy Policy or our data practices, contact us at:

2. Scope of this Policy

This Privacy Policy applies to the public website hosted at a3ro-dev.github.io/qenlo (including documentation pages and landing assets) and direct communications with the project maintainers. It explains how we collect, process, and safeguard information in compliance with:

3. Information We Collect and Process

A. Core Software & SDKs (Local-First Guarantee)

When you download, compile, or embed Qenlo (e.g., via Cargo, npm, PyPI, or local builds), Qenlo operates strictly locally. It does not install background telemetry daemons, does not report installation events, does not track feature usage, and transmits zero user data. Any telemetry capability (such as OpenTelemetry OTLP tracing for benchmarks) is strictly opt-in and controlled by the host application.

B. Website Infrastructure & Technical Server Logs

When accessing this website, our hosting infrastructure provider (GitHub Pages operated by GitHub Inc. / Microsoft Corporation) and our content delivery network (Amazon Web Services CloudFront) automatically log standard HTTP protocol requests. These logs may contain:

Legal Basis: Processing this server data is justified under GDPR Article 6(1)(f) (Legitimate Interests) to maintain network security, mitigate Distributed Denial of Service (DDoS) attacks, ensure server stability, and deliver requested content.

C. Direct Inquiries and Form Submissions

If you submit an inquiry through our contact form or email us directly, we collect only the information strictly necessary to process your request:

Legal Basis: Processing is based on your explicit, affirmative consent pursuant to GDPR Article 6(1)(a) and Section 6 of the Indian DPDP Act 2023. We do not use your contact information for unsolicited commercial marketing or newsletters without separate, prior opt-in consent.

6. Cookies and Local Storage

This website employs only strictly necessary technical storage (via browser localStorage) required to operate the user interface:

Because these storage items are strictly necessary to deliver services explicitly requested by you, they are exempt from consent requirements under Article 5(3) of the EU ePrivacy Directive. For further information, see our dedicated Cookie Policy.

9. Data Retention and Security

We retain submitted communication data only as long as necessary to fulfill the specific purpose of the inquiry or to satisfy statutory record-keeping obligations. Server logs maintained by hosting providers are automatically purged or rotated on standard rolling schedules (typically 30 to 90 days). We implement reasonable organizational and technical safeguards, including HTTPS TLS 1.3 encryption in transit, strict repository access controls, and minimization of retained data.

10. Children's Privacy
