Cart Cooler (La Nevera)

Open-source, zero-telemetry friction tool against impulsive online purchases (GNU GPLv3). 100% local, no CDNs, no tracking.

Tired of late-night dopamine shopping and buyer's remorse? Cart Cooler restores friction and intentionality to online shopping by intercepting purchase buttons and running your buying decisions through a reflective, deterministic triage tree. Instead of imposing rigid, frustrating blocks on essential items, Cart Cooler asks four binary questions to separate genuine needs from impulsive urges. Approved necessities go through immediately; spontaneous splurges are put on ice. Key Features Guided Triage Decision Engine: Evaluates critical need, liquidity, past consideration time, and cost-per-use before letting you spend. Smart Cooling-Off Quarantine: High-risk impulse items are frozen for 48 hours, 7 days, or 30 days in "The Cooler" with live countdown tickers. Direct Purchase Elimination: Strips out impulsive shortcuts ("Buy Now", "1-Click", direct checkout) via instant DOM guards and continuous MutationObserver protection. Anti-Bundle Enforcement: Blocks deceptive "Frequently Bought Together" bundles, requiring you to evaluate each product individually. Mandatory Product Inspection: Direct-cart additions from search grids or carousels are redirected to the full product detail page, breaking mindless browsing loops. Price History Verification: Direct one-click integration with CamelCamelCamel on Amazon to verify whether that "deal" is actually a discount. 24-Hour Store Lockout ("Bunker Mode"): An optional circuit-breaker that temporarily locks access to online stores if you trigger multiple impulse freezes in a rolling 24-hour window. Financial Impact & Savings Dashboard: Track your progress with detailed analytics on potential savings, reflective spending, and money permanently rescued from impulse traps. Export your history to CSV at any time. How the Triage Works Critical Need: Is it an urgent replacement or daily staple? (Yes ➔ Immediate Purchase). Budget Check: Is money explicitly allocated without hitting savings? (No ➔ 30-Day Cool-Down). Temporal Friction: Have you considered it for more than 7 days? (No ➔ 48-Hour Cool-Down). Cost Per Use: Will you use it weekly for the next 3 months? (Yes ➔ Immediate Purchase / No ➔ 7-Day Cool-Down). 100% Private, Auditable, and Free (GNU GPLv3) Most shopping extensions make money by tracking your behavior, injecting affiliate tags, or selling your data. Cart Cooler takes the opposite approach: Zero Telemetry: No analytics, no logging, no heartbeat requests, and no tracking IDs. 100% Local Execution: All data, timers, and logs reside exclusively in your browser's local sandbox (chrome.storage.local). Zero Remote Assets: No external CDNs, third-party scripts, or tracking pixels. Open Source: Licensed under the GNU General Public License v3.0. Inspect every single line of code on GitHub. Keyboard-Friendly Workflow Navigate the entire triage modal without touching your mouse using intuitive hotkeys: Y (Yes), N (No), Backspace / Left Arrow (Back), and Escape (Cancel).
