Terms of Use

• You must be 18 or older to hold an account.
• One person, one account. Operating more than one to take the same survey twice is fraud, and it ends both accounts and forfeits the balance.
• The details you give must be true: researchers target studies by them and pay for that accuracy.
• You are responsible for what happens under your login. Tell us immediately if you think someone else has it.

You are paid in SURDA for work you complete and that is approved:

• The reward is shown before you start, and does not change once you begin.
• Payment follows approval by the researcher. A response can be rejected for straightlining, contradictory answers, or answers that do not address the question.
• A rejected response can be disputed, and is reviewed by validators who are not the researcher.
• You are paid once per survey. Submitting again does not pay again.
• A cash-out has a minimum for each method, shown before you choose it.
• We only offer payout methods we can actually settle.

Your answers become part of a dataset the researcher owns, and may be resold on the Surdatics Data Marketplace in anonymised form. You keep no ownership of a response once it is paid for, and we cannot recall it from a buyer afterwards.

• You fund the reward pool up front, and respondents are paid from it.
• Unspent rewards are refunded to you when a survey closes.
• You may reject a response, with a reason. Rejecting responses in order to avoid paying for work that met the brief is a breach of these terms.
• You own the dataset your survey produces and may list it on the Surdatics Data Marketplace.
• You may not use Surdatics to collect data you intend to use for a purpose you concealed from respondents.

Your obligations to respondents. You are the data controller for the responses you commission. You must have a lawful purpose, you must not ask for more personal data than that purpose needs, and you must not ask respondents to identify themselves in free text in order to route around our anonymisation.

The Surdatics Data Marketplace carries two kinds of data, labelled distinctly:

• Collected on Surdatics — gathered here from consenting respondents who were paid, with every answer anchored on the blockchain.
• Brought by the seller — collected elsewhere and listed here. We verify what we can and disclose what we cannot. The seller warrants its lawful origin; we did not witness its collection.

If you sell: you warrant that you hold the rights to the data, that it was collected lawfully and with consent, that it is not scraped, and that it contains no direct identifiers. You indemnify us against claims arising from a breach of that warranty. We take a commission on each sale, shown before you list.

If you buy: you may not attempt to re-identify any individual, and you may not resell the dataset as your own collection. Access ends immediately if you do.

Every dataset passes automated checks before it is listed:

• Direct identifiers are searched for in every field, including free text, and a dataset containing them is refused.
• A dataset said to be collected on Surdatics is checked against the real responses.
• Small datasets are flagged, because a few detailed rows can identify people.
• The seller confirms lawful origin and consent, and that is recorded against their account.

Passing these checks is not our warranty that a seller's dataset is lawful. The seller carries that, and buyers are told which kind of data they are buying.

• Use more than one account, or answer a survey more than once.
• Answer without reading — straightlining, random answers, or automated submissions.
• Upload scraped data, or data you do not hold the rights to.
• Attempt to re-identify individuals in any dataset.
• Collect data for a purpose you hid from respondents.
• Probe, scan or attack the platform, other than under a security disclosure arrangement agreed with us in writing.
• Resell platform access, or use the API to build a competing index of our respondents.

• SURDA is the unit of account on the platform. Its rate against the dollar is shown wherever a conversion is made.
• Researchers fund in fiat or stablecoin. Respondents are paid in SURDA and may cash out to the methods available to them.
• We take a commission on survey rewards and on dataset sales. Both are shown before you commit.
• A payout can be reversed if the work it paid for is found to be fraudulent.
• Fees charged by a bank or a blockchain are not ours and are not refundable by us.

We provide Surdatics as it is. We do not warrant that a survey will reach a particular number of people, that a dataset will suit your purpose, or that the service will be uninterrupted.

Nothing here limits liability for fraud, for death or personal injury caused by negligence, or for anything else the law does not permit us to limit. Subject to that, our total liability to you is limited to the amount you paid us in the twelve months before the claim.

You can close your account at any time. Any balance above the cash-out minimum can be withdrawn first; below it, we will tell you plainly rather than leave you guessing.

We may suspend an account for fraud, for a breach of these terms, or where required by law. Where we do, we say why, and you can dispute it.

These terms are governed by the laws of the Federal Republic of Nigeria. If you are a consumer in the EU or UK, this does not deprive you of the protection of your own country's mandatory consumer law.
