3. Description of the Service

3.1. IOStamp provides blockchain-based timestamping services that allow users to create a permanent, tamper-proof record proving that specific digital content existed at a particular point in time.

3.2. The Service operates as follows:

  • (a) You submit a cryptographic hash (SHA-256) of your Content to our API.
  • (b) IOStamp anchors that hash to the Bitcoin SV (BSV) blockchain.
  • (c) The Service returns a transaction ID, timestamp, and verification URL.
  • (d) A visual Badge may be generated client-side in your browser.

3.3. Your Content never leaves your device. Only the cryptographic hash — a mathematical fingerprint — is transmitted to and processed by IOStamp. We do not receive, store, view, or have access to your original files.

3.4. IOStamp does not provide legal advice, notarization services, or copyright registration. The Service provides evidence of existence at a point in time, which may be used to support legal claims at your discretion.

4.3. All payments are processed through Stripe, Inc. By subscribing, you agree to Stripe's terms of service in addition to these Terms.

4.5. IOStamp reserves the right to modify pricing with at least 30 days' notice. Existing Subscriptions will not be affected until their next renewal date.

4.6. If payment fails, IOStamp may suspend access to paid features. Your data (hashes and metadata) will be retained for 90 days, after which it may be deleted.

4.7. Promotional discounts and coupon codes are subject to specific terms communicated at the time of offer and may be limited in duration, availability, or eligibility.

5. Free Tier and Stamp Allocation

5.1. New Accounts receive a one-time allocation of free Stamps as specified at the time of registration.

  • (c) Use the API to build a competing timestamping service.
