Introduction
AltStack is built with a privacy-centric, zero-cloud mindset for personal workflow data. Our goal is to help you discover software alternatives without turning your research session into a tracking profile. The catalog itself is served from our infrastructure, but your curation choices—what you save, reject, or filter—are treated as yours first.
Data Collection (Local-First)
Many AltStack features are intentionally local-first. That means the following preferences are stored inside your browser environment, not uploaded to our master servers as a personal configuration archive:
- My Stack saves and export state you choose during a session
- Active filter pills and view-mode selections while you browse
- Focus-mode progress markers (such as cards you have already reviewed) for continuity within your visit
We do not maintain a centralized account of your stack composition or filter profile tied to your identity. If you clear site data in your browser, that local state is removed with it.
Outbound Referral Links
When you click primary action buttons on alternative cards (for example, Go to [Product Name]), you leave AltStack and enter a standard partner or vendor destination. Those pathways may include minimal outbound routing flags—such as referral or affiliate parameters—so we can attribute traffic and help fund directory maintenance, hosting, and research operations.
- Referral routing does not grant AltStack access to your activity on the vendor site
- Each destination is governed by that provider's own privacy policy
- We disclose this relationship openly so you can make an informed click
No Invasive Analytics
AltStack rejects intrusive third-party cross-site trackers and identity-harvesting data brokers. We do not sell personal profiles, stitch your AltStack usage into ad-network audiences, or deploy hidden fingerprinting pixels for surveillance-style analytics.
If we introduce optional, privacy-respecting telemetry in the future, it will be documented here first—with clear opt-out controls and a narrow scope limited to reliability and catalog quality.
Questions or Updates
This policy may evolve as AltStack grows. Material changes will be reflected on this page. If you have privacy questions, contact us through the channels listed on the main site when available.
