The Vanishing Agreement Problem
You signed up for a service, agreed to specific terms, and made decisions based on those promises. Then the company quietly updated their terms of service — removing the guarantee, changing the refund policy, adding fees, or restricting features you were promised.
When you complain, they point to the current terms on their website. But those are not the terms you agreed to. The problem: how do you prove what the terms said on the day you accepted them?
Why This Happens More Than You Think
Companies modify their terms of service constantly. Studies have shown that major platforms update their ToS an average of several times per year, and most users are never meaningfully notified. Changes include:
- Removed guarantees — Money-back promises quietly disappear
- Added fees — Free features become paid
- Reduced service levels — SLA commitments are loosened
- Changed dispute resolution — Arbitration clauses are added
- Modified cancellation policies — Easy cancellation becomes difficult
- Altered data usage rights — Your data gets shared with new parties
Most users discover changes only when they try to exercise a right that no longer exists.
The Legal Framework
Contract Formation
When you accept terms of service, a contract is formed based on those specific terms at that specific moment. The company cannot unilaterally modify the contract without:
- Proper notice to you
- Your acceptance of the new terms (explicit or through continued use, depending on jurisdiction)
- Consideration (something of value exchanged)
The Proof Problem
Courts will enforce the original terms — but only if you can prove what they said. The company controls the website and can (and does) overwrite previous versions without maintaining accessible archives.
What Courts Need
To prevail in a dispute over changed terms, you typically need to show:
- What the terms said when you accepted them
- When you accepted those specific terms
- That the terms have since changed
- That the change is material to your claim
How to Capture Terms of Service as Evidence
Before You Sign Up (Prevention)
The best time to capture terms is the moment you agree to them:
1. Capture the full terms page.
Before clicking "I Agree," capture the complete terms of service page, including:
- The full URL
- The complete text of all terms
- The date visible on the page (if shown)
- Any version number or "last updated" date
- Related pages (privacy policy, refund policy, SLA)
2. Use forensic-grade capture.
A forensic web capture creates a verified record with:
- SHA-256 hash proving content integrity
- Blockchain timestamp proving the capture date independently
- HAR network logs proving the page was genuinely served from the company's domain
- TLS certificate confirming the server's identity
- Complete DOM snapshot preserving every element of the page
TrueSnap captures all of this in seconds. One click before you agree creates an immutable record of exactly what you were agreeing to.
3. Capture the sign-up/checkout page.
The page where you click "agree" often summarizes key terms (pricing, trial length, refund rights). Capture this too.
4. Save confirmation emails.
Post-signup emails often reference specific terms or promises. Keep these.
After You Discover Changes
If you already agreed and now suspect the terms have changed:
1. Capture the current terms immediately.
Even if they have already changed, documenting what they say now establishes that a modification occurred.
2. Check the Wayback Machine.
web.archive.org may have snapshots of the terms page from around the time you signed up. Capture any relevant archived versions forensically.
3. Search for cached versions.
Google Cache and other search engine caches may retain older versions.
4. Check your email.
Look for the original welcome email, confirmation, or any communication referencing specific terms.
5. Search community forums.
Other users may have discussed or quoted the original terms in forums, reviews, or social media posts.
6. Check your browser history.
Your browser may have timestamps showing when you accessed the terms page.
Building Your Case
Document the Timeline
- When you signed up (date and evidence of sign-up)
- What the terms said at that time (forensic capture or reconstructed evidence)
- When the terms changed (current terms show a "last updated" date)
- What specifically changed (side-by-side comparison)
- How the change harms you (lost money, lost features, lost rights)
Common Scenarios and Approaches
Subscription service raised prices without notice: Capture the current pricing page, locate your original sign-up confirmation showing the original price, and document any communications (or lack thereof) about the price change.
SaaS company removed features you were paying for: Capture the current feature page, find marketing materials or feature lists from when you subscribed, and document when features stopped working.
E-commerce site changed refund policy after purchase: Capture current refund terms, find your order confirmation referencing the original refund policy, and document your refund request and denial.
Service added forced arbitration clause: Capture current terms showing arbitration, document the original terms without it, and note that you were never meaningfully notified or given a chance to opt out.
Preventive Strategies for Businesses and Consumers
For Consumers
- Capture terms at sign-up for any service where money or rights are involved
- Capture pricing pages before making purchase decisions
- Set calendar reminders to periodically re-capture terms for ongoing subscriptions
- Save all confirmation emails in a dedicated folder
- Monitor ToS change notifications (services like tosdr.org track some platforms)
For Businesses
- Capture competitor terms to prevent bait-and-switch accusations against your business
- Capture vendor terms when signing contracts with service providers
- Document partnership agreements with web captures of referenced online materials
- Maintain a terms archive for your own terms to demonstrate good faith
Legal Options When Terms Change
Depending on your jurisdiction and situation:
Breach of contract claim. If you can prove the original terms constituted a binding agreement and were modified without proper consent.
Consumer protection complaint. Many jurisdictions have unfair business practice laws that cover unilateral contract modifications.
Regulatory complaint. The FTC (US), CMA (UK), and equivalent bodies investigate deceptive business practices.
Class action. If many consumers were affected by the same change, collective action may be appropriate.
Chargeback. For credit card payments, you may be able to dispute charges based on services not as described.
Start Capturing Today
The lesson is simple: if you are agreeing to terms that affect your money, rights, or business, capture those terms the moment you agree. The thirty seconds it takes to create a forensic capture can save you months of dispute resolution — and gives you proof that cannot be challenged even after the company rewrites their entire website.
