How Fortnite Chest Tracker Works: Features, Storage & Limits
Learn how fortnitechesttracker.app counts chests, saves personal map pins and exports JSON, with clear limits on account access and recovery.
Last updated: 2026-11-13
Fortnite Chest Tracker at fortnitechesttracker.app is a free, independent browser tool for manually counting Treasure, Rare and Sprite chests. It also provides a reward checklist, a probability calculator, personal island map pins and sourced event-time guides. No Epic Games login is required. Your personal records are saved in this browser. JSON export is available; importing or restoring a JSON file inside the site is not supported.
Features at a glance
| Feature | What you can do | Important limit |
|---|---|---|
| Manual chest log | Count Treasure, Rare and Sprite openings separately | You enter openings yourself; the site does not read game activity |
| Reward checklist | Mark rewards you have found | Checkmarks record your notes; they do not verify or claim rewards |
| Personal island plan | Add, rename, reorder and mark pins visited | Personal pins are not verified chest spawn coordinates |
| Probability calculator | Estimate a chance across a chosen number of openings | Estimates depend on the stated rate and assumptions; rewards are not guaranteed |
| JSON backup | Download a copy of your saved log and readable map data | Export only; no in-site import or automatic restore |
| Event guide | Compare UTC, ET, UK and Beijing times | Source status and uncertain start times are shown explicitly |
Count the chests you actually open
Open the homepage counter and add each opening to the appropriate chest type. The minus button corrects mistakes; the +10 button helps you enter a batch you already counted. Counts stay between zero and 1,000,000. Progress goals are personal tracking targets, not guaranteed rewards or verified quest requirements.
To use the keyboard, select Use keyboard on a homepage counter panel. While that panel has focus, Space adds one and Enter removes one. The browser tab must be active. The site cannot listen to game keypresses while Fortnite has focus. Holding a key does not repeatedly change the total, and other buttons keep their normal keyboard behavior.
If you need help finding the in-game quest figures, follow how to check chest counts. A manual log cannot recover openings you did not record or retrieve a permanent account history.
Keep your reward notes separate from claims
On the homepage, choose a reward week and check the items you have found. Checkmarks change your local log. They do not inspect your Fortnite inventory, send a claim or unlock Pirate Shop access. The five-week reward overview distinguishes checked reward information from rotations that have not been announced or verified.
The site does not generate tokens, activate accounts or redeem prizes. Use Fortnite’s own prompts for eligibility, activation and redemption. The token guide explains the reported windows and their sources.
Make a personal map route
On the chest map, choose Chest, Rare chest or Waypoint, select Add pin, then tap the map. You can name a stop, move it up or down in your route, mark it visited or delete it. There is room for up to 100 personal pins. Drag to explore, use the zoom buttons for 100%–400% zoom, and reset the view when needed. Keyboard controls are described beside the map.
Layer switches hide selected pin types. Route lines connect your stops in your chosen order; they do not calculate terrain, safe paths, storm movement or an optimal route. Hidden stops still count toward your route progress. The area-count diagrams and search notes below the planner are separate, dated community-source information. Their numbered markers show approximate area centers, not individual guaranteed containers.
Understand probability estimates
The probability calculator models independent attempts at a fixed per-opening probability. Its cumulative chance is 1 − (1 − p)^n, where p is the probability per opening and n is the number of attempts. A past miss does not increase the next opening’s probability in this model. Calculator inputs do not change your saved chest counts.
Check the cited source and match conditions before applying a rate. Event multipliers or eligibility rules can change the assumptions. The calculator does not predict your next reward or promise that any number of openings will produce a prize.
Save and export your own records
Counts, reward checkmarks, activation time and personal map pins are stored in this browser’s local storage. Another browser, private window or device has its own records. There is no account sync or server-side cloud backup. The tool does not upload the contents of your manual log or map plan for account storage.
Use Export JSON on the homepage record section or counter page to download your own backup. It contains the tracker record and readable map data, with a format version and export timestamp. Unavailable or unreadable map storage is identified in the file. Keep the file somewhere safe: clearing site data removes browser records, and the website currently cannot import that file to restore them. When storage is blocked, the interface warns that changes may last only for the current visit.

Sources, updates and contact
This site is an independent fan-made tool and is not affiliated with Epic Games. Game rules and official account actions belong to Epic. Guide pages link to their sources and show which information is official, community-reported or uncertain. A source-check date records a review; it is not a promise that an event cannot change afterward. Use the event timetable and current in-game announcements before planning a session.
