Version 2026-11-11.
This notice explains what personal data oto collects when you buy an otoSpeech data pack, and what we do with it.
1. Who is responsible
otoearth, Inc., 1876 Bush St, San Francisco, CA 94109, United States, decides how the personal data described here is used. Contact: agent@oto.earth.
This notice covers buyers and people who sign in to the store. It does not cover the speakers in the datasets, whose recordings are handled under the consent they gave when recording.
2. What we collect
- From Google when you sign in: your name, email address, and Google account ID.
- From the order form: the licensee's name, whether it is an organization or an individual, its country, your name if you order for an organization, the notice email, and your Hugging Face username.
- About each order: the pack, price, payment status, the version of the terms accepted, and the time of acceptance.
- From Stripe: confirmation of payment, billing name and address, and tax ID if you enter one. We do not receive your card number.
- From your browser: IP address, browser type, and the pages requested, as server logs. We use the country of your IP address to suggest the country on the order form.
3. What we use it for
- To take the order, issue the license, and deliver the data.
- To send the invoice, Removal Notices and other dataset updates, and the invite to the buyers' group.
- To answer your questions.
- To prevent fraud and misuse of the data.
- To keep the tax and accounting records the law requires.
4. Our legal grounds
Where the law asks for a legal ground, we rely on these:
- the contract with you, for taking the order, issuing the license, delivering the data, and sending notices about it;
- our legal duties, for tax and accounting records; and
- our legitimate interests, for preventing fraud and misuse and for telling our customers about new datasets, which you can stop at any time.
We need the information on the order form to sell you a pack. We do not make decisions about you by automated means alone.
5. News about new datasets
As a customer you get an email at the notice address when we release a new dataset. To stop these, untick the box at checkout, use the link in any of these emails, or write to agent@oto.earth. Notices about your order and your data do not depend on this choice.
6. Cookies
The store sets one cookie, oto_session, to keep you signed in. It lasts 7 days and is not used for advertising.
It also keeps a mark in your browser's storage, oto-store-signed-in, so the header can show the link to your purchases. The mark holds no personal data and is removed when you sign out.
7. Who we share it with
We share personal data only with companies that provide services to us, and only as needed for those services:
- Google, for sign-in;
- Stripe and Link, for payment, tax, receipts, invoices, and questions about a payment;
- Hugging Face, to give your account access to the data;
- Supabase, for the order database;
- Vercel, for hosting and site analytics;
- Resend, for sending email; and
- oto Japan G.K. (oto Japan合同会社), our affiliate in Japan, whose staff help run the store and support buyers.
We also share it when the law requires it. We do not sell personal data.
8. Where it is processed
Personal data is processed in the United States and Japan, and in other countries where the companies above operate. Where the law requires it, we use approved safeguards such as standard contractual clauses for these transfers.
9. How long we keep it
We keep order and license records for as long as the license lasts and for 7 years after that for tax and legal reasons. We delete server logs within 90 days.
10. Your rights
You can ask us for a copy of your personal data, ask us to correct or delete it, or object to how we use it. Write to agent@oto.earth. We answer within 30 days.
We may need to keep some records, such as invoices and proof of the license, even after a deletion request, where the law requires it.
Depending on where you live, you may also have the right to complain to your data protection authority.
If you live in California, you have the right to know what personal information we collect, to have it corrected or deleted, and not to be treated differently for using these rights. We do not sell or share personal information for advertising.
11. Children
The store is not for people under 18.
12. Changes
If we change this notice, we post the new version here with its date. If the change is significant, we email the notice address.
