HashCam provides the timestamping service “as is” without warranties of any kind, express or implied, including but not limited to accuracy, reliability, or fitness for a particular purpose.

Impact Makers BV and its affiliates disclaim all liability for any loss, damage, or legal consequences resulting from the use or inability to use the HashCam service or any certificates issued.

HashCam processes personal data as described in its Privacy Policy. This Disclaimer does not cover your data-protection rights or our obligations under that Policy.

1. Technical Infrastructure Disclosure

When you submit a file or document to HashCam, we compute a cryptographic “hash” of its contents and record that hash on the public Ethereum blockchain. This timestamping provides a tamper-evident proof of existence as of the time the hash is written. While we strive to ensure continuous availability, the Ethereum network is maintained by third parties and may, on rare occasions, be subject to forks, downtime, or other technical disruptions.

2. Blockchain Dependency

The integrity and accessibility of timestamp certificates depend on the continued availability and operation of the underlying Ethereum blockchain infrastructure, including:

•    Network consensus mechanisms (Proof of Stake);

•    Third-party node availability (e.g. Infura, Alchemy);

•    Ethereum client functionality (e.g. Geth, Nethermind);

HashCam does not control or operate the Ethereum blockchain. We cannot guarantee permanent uptime, unaltered structure, or future access to historical transactions. Downtime, chain forks, or  e.g. testnet deprecation are possible and beyond our control.

3. Future Migration

HashCam reserves the right to migrate its timestamping service to:

•    A Layer-2 network or sidechain;

•    Another public or permissioned blockchain;

•    An off-chain notarisation protocol.

In such cases, new certificates may refer to different blockchain explorers or smart contract addresses. However, previously issued certificates will remain valid to the extent that public access to the recorded transaction remains available.

We will make reasonable efforts to notify users in advance of any material change to the timestamping infrastructure.

In case of migration to a new blockchain or network, future timestamp certificates will reference the new infrastructure. While existing certificates remain valid if their transactions are publicly accessible, users may need to use different verification tools or contact support for assistance.

4. Verification Tools and Responsibility

HashCam provides certificate links to blockchain records via public blockchain explorers (e.g. https://etherscan.io). These third-party tools are not under our control. If they become unavailable or inaccurate, users may need to manually verify hashes using other tools or contact our support team for assistance.

You (or any third party) can later verify a certificate by dropping the original media file into our browser-based verifier at https://hashcam.io/verify/. All hashing is performed locally in your browser, no copy of your media is uploaded or retained, and the resulting hash is compared against the hash stored on our public smart contract.

Users are responsible for:

•    Keeping their original file unchanged;

•    Safely storing the PDF certificate;

•    Verifying hashes independently when required.

Loss, alteration, or destruction of original media files and timestamp certificates may render verification impossible, for which HashCam accepts no responsibility.

To independently verify the SHA-256 hash of your original file, you can use trusted online calculators or software, for example:

•    https://md5file.com/calculator

•    https://passwordsgenerator.net/sha256-hash-generator/

For desktop users, tools such as ‘HashCalc’ (Windows), ‘7-Zip’ (Windows), or the ‘shasum’ command (Mac/Linux Terminal) are reliable options.

Users remain responsible for keeping their original files unchanged, safely storing the PDF certificates, and verifying hashes as needed.

5. No Guarantee of Long-Term Record

We cannot guarantee indefinite availability of any specific transaction on the public Ethereum blockchain. HashCam is not liable for the removal, obsolescence, or inaccessibility of blockchain entries due to:

•    Chain resets or archive pruning;

•    Block explorer shutdowns;

•    Smart contract upgrades;

•    External interference or tampering.

6. No Legal Certification

This service is a technical timestamping aid and not a regulated time-stamp under Regulation (EU) No 910/2014 (eIDAS). It does not replace official notarisation or court-certified digital evidence procedures.

7. Governing Law and Jurisdiction

This Disclaimer and any disputes arising from or related to HashCam shall be governed by Belgian law. Disputes shall be subject to the exclusive jurisdiction of the courts of Leuven, Belgium, provided that, for any User qualifying as a consumer under EU law, proceedings may also be brought before the courts of the User’s place of residence in accordance with Art. 18(1) of Regulation (EU) No 1215/2012 (Brussels I bis).
