Ashta asks for unusually personal things — your time and place of birth, your voice, your heart rate. A project whose whole claim is honest measurement owes you a plain account of what happens to them. This is that account.

This policy covers theashtaproject.com, the membership area at members.theashtaproject.com, and the forms and studies we run through them. The Ashta Project decides what data is collected and why, and is responsible for it.
If you only read the site and never fill in a form, we do not ask you for anything and we do not build a profile of you.
We rely on different legal grounds depending on what the data is for:
Health-related and biometric data is handled to a special-category standard: collected only on your explicit consent, separated from your identity as early as we can, and never used for a purpose you were not told about.
Data that goes into a study is separated from your name and email and given a code. Analysis is run on the coded data. Published results are reported at the level of the group, never as an identifiable individual.
We hold the key that links the code back to you, because you have the right to ask us to delete or extract your data and we cannot honour that without it. That key is kept separately from the research data and access to it is restricted.
The commitments in our research standards — hashing, de-identification, documented chain of custody, no medical or diagnostic claims — apply to everything described on this page.
Being filmed is not part of being a member. It is asked for on its own, it requires your written consent, and you can take part in every experiment without ever appearing on screen. Nobody is filmed who has not agreed in writing to be.
Consenting to appear is not the same as consenting to research, and neither implies the other. You can withdraw filming consent — see the documentary page for how filming works in practice.
We use a small number of service providers. They process data on our instructions and are not permitted to use it for their own purposes.
youtube-nocookie.com), which does not set tracking cookies unless you press play. If you play a video, YouTube's own terms apply to that playback.We do not sell your data. We do not share it with advertisers. We do not trade it with other organisations.
The providers above operate internationally, so your data may be processed outside the country you live in. Where that happens we rely on the transfer safeguards those providers offer under their own data-processing terms.
The principles we hold to:
You can ask us to:
Exercising any of these is free, and asking costs you nothing in standing with the project.
You can leave a study at any point, without giving a reason. Tell us and we will stop collecting from you immediately. You can additionally ask us to remove the data you have already contributed, and we will — unless it has already been aggregated into a published analysis, in which case we will tell you plainly that it cannot be unpicked, and we will remove everything that still can be.
Leaving a study does not end your membership, and does not affect anything else you take part in.
Email contact@theashtaproject.com and say what you want. We will confirm receipt and act on it.
We have not appointed a Data Protection Officer. Enquiries go to the address above and are dealt with by the project directly.
If you think we have handled your data badly, tell us first — we would rather fix it than have it escalated. You also have the right to complain to the data-protection regulator in your country, and you do not need our agreement to do so.
Ashta is not intended for children, and we do not knowingly collect data from them. If you believe a child has given us data, contact us and we will delete it.
If we change how we handle your data we will update this page and change the date at the top. Where a change materially affects data you have already given us, we will tell you directly rather than rely on you noticing.
