Your materials. Your browser.

Your plan stays here

Project quantities, owned materials and crafting choices are saved in this browser under sinistous-gw2-planner-v1. They are not sent to Sinistous or ArenaNet. Different devices and browsers have separate plans. Clearing site data can erase the plan.

Public API requests

When you load or refresh prices, your browser requests public item prices directly from api.guildwars2.com. That request contains the catalog’s public item IDs, not your quantities or account information. ArenaNet also serves item and profession images from render.guildwars2.com. These services receive ordinary connection details such as your IP address. The site never asks for a game API key.

Backups, deletion and recovery

Download backup saves your plan to a file on your device. Restore validates the file and shows a preview before applying it. Reset plan clears the saved quantities and choices; Undo last change can restore the previous in-session state. To remove all local data, clear this site’s browser storage. Delete downloaded backups separately.

Optional accounts and Premium

If you choose to sign in with Google or Discord, we store your provider account identifier, name, email address and profile image in a site-specific Neon database. The authentication library may store provider tokens for the linked account. Secure session and sign-in cookies keep you signed in. Your password stays with the provider; this site does not request your game credentials.

Network Premium is matched by your verified email in a shared membership database. Stripe processes subscriptions and billing details; Sinistous stores membership and Stripe customer/subscription references, not payment card numbers. Signing in does not upload or synchronize your browser-local plan. Clearing browser storage removes local plans and cookies, but does not delete your server account or cancel a subscription. Use Manage subscription to cancel renewal.

Hosting

Vercel hosts the site, Cloudflare provides DNS, and Neon stores account records. Infrastructure providers may process standard connection and security logs. All current tools remain free. This release has no advertising or application analytics. External providers and other network sites have their own data practices.
