Trackless Links at ACM WebSci 2026: Free Codes to Mark the CRED-1 Presentation
The CRED-1 open domain credibility dataset is being presented at ACM WebSci 2026 in Braunschweig. To mark the occasion, the Trackless Links team is releasing free promo codes for the app, which uses CRED-1 to warn users about low-credibility links on-device.
Stand: 24. Mai 2026
CRED-1 is being presented at the 18th ACM Web Science Conference (ACM WebSci 2026) in Braunschweig, Germany. CRED-1 is an open, reproducible domain credibility dataset that combines multiple openly-licensed source lists with computed enrichment signals to flag mis- and disinformation domains. It covers 2,672 domains and is designed specifically for on-device, client-side deployment with no server calls.
The iOS app Trackless Links is the first production integration of CRED-1: when a user opens a link, the Safari extension strips tracking parameters on-device and, in the same pass, checks the destination domain against the CRED-1 score so the user can be warned before they land on a known low-credibility source. Same on-device-only model, no cloud lookups, no analytics.
To mark the WebSci 2026 presentation, the Trackless Links team is releasing a batch of free promo codes for the app. Claim one with the card above while they last.

What CRED-1 does inside Trackless Links
CRED-1 ships as a static JSON snapshot bundled with the app. When the Safari extension processes a URL, it:
1. Strips known tracking parameters (utm_source, fbclid, gclid, mc_eid and friends) before the destination site is contacted. 2. Looks up the cleaned destination domain in the bundled CRED-1 snapshot. 3. If the domain is flagged as low-credibility, surfaces a lightweight warning in Safari so the user can decide whether to proceed.
Everything runs locally. No URL ever leaves the device, no telemetry is collected, and there is no account.
Why this matters
Most browser-side credibility tools call out to a cloud service for each URL, which trades one privacy problem (trackers) for another (a third party now sees every link you visit). CRED-1 is small enough to ship inside the app, which keeps the privacy guarantees intact and makes the system fully reviewable: anyone can audit the dataset, regenerate it from the pipeline scripts, and contribute corrections through GitHub.
How the codes work
Each code unlocks Trackless Links on the App Store for one Apple ID. Single-use, with an Apple-set expiration (usually 4 weeks). Redeem under App Store > your profile picture > Redeem Gift Card or Code.
One code per person. Codes are for use, not for resale. If a code you claim is expired or already used, contact the Trackless Links team and they will swap it.
Feedback welcome
If you spot a domain CRED-1 should cover, a tracking parameter the extension misses, or anything else worth fixing, open an issue at github.com/aloth/trackless-links/issues. For CRED-1 dataset issues, use github.com/aloth/cred-1/issues.
