Terms of Use

Last updated October 12, 2026

We are Ryan Sieh ("Company," "we," "us," "our"), operating Osko from 2254 Cannery Loop, Davis, CA 95616.

We operate the website https://osko.app (the "Site") and its forum (together, the "Services"). These legal terms (the "Legal Terms") govern the Services. They do not govern the Osko app: Apple licenses the app to you under its Licensed Application End User License Agreement, and Osko Pro purchases, renewals, cancellations and refunds are handled by Apple under that agreement.

Osko is an iPhone reminder that comes back until you answer it. You type or say a task, Osko gives it a time, and the nudge returns with the same words until you tap Done.

You can contact us by phone at 213-429-2706, by email at support@osko.app, or by mail to 2254 Cannery Loop, Davis, CA 95616, United States.

These Legal Terms constitute a legally binding agreement made between you, whether personally or on behalf of an entity ("you"), and Ryan Sieh, concerning your access to and use of the Services. You agree that by accessing the Services, you have read, understood, and agreed to be bound by all of these Legal Terms. IF YOU DO NOT AGREE WITH ALL OF THESE LEGAL TERMS, THEN YOU ARE EXPRESSLY PROHIBITED FROM USING THE SERVICES AND YOU MUST DISCONTINUE USE IMMEDIATELY.

The Services are intended for users who are at least 13 years of age. All users who are minors in the jurisdiction in which they reside (generally under the age of 18) must have the permission of, and be directly supervised by, their parent or guardian to use the Services. If you are a minor, you must have your parent or guardian read and agree to these Legal Terms prior to you using the Services.

We recommend that you print a copy of these Legal Terms for your records.

1. Our services

The information provided when using the Services is not intended for distribution to or use by any person or entity in any jurisdiction or country where such distribution or use would be contrary to law or regulation or which would subject us to any registration requirement within such jurisdiction or country. Accordingly, those persons who choose to access the Services from other locations do so on their own initiative and are solely responsible for compliance with local laws, if and to the extent local laws are applicable.

The Services are not tailored to comply with industry-specific regulations (Health Insurance Portability and Accountability Act (HIPAA), Federal Information Security Management Act (FISMA), etc.), so if your interactions would be subjected to such laws, you may not use the Services. You may not use the Services in a way that would violate the Gramm-Leach-Bliley Act (GLBA).

2. Intellectual property rights

13. Term and termination

These Legal Terms shall remain in full force and effect while you use the Services. WITHOUT LIMITING ANY OTHER PROVISION OF THESE LEGAL TERMS, WE RESERVE THE RIGHT TO, IN OUR SOLE DISCRETION AND WITHOUT NOTICE OR LIABILITY, DENY ACCESS TO AND USE OF THE SERVICES (INCLUDING BLOCKING CERTAIN IP ADDRESSES), TO ANY PERSON FOR ANY REASON OR FOR NO REASON, INCLUDING WITHOUT LIMITATION FOR BREACH OF ANY REPRESENTATION, WARRANTY, OR COVENANT CONTAINED IN THESE LEGAL TERMS OR OF ANY APPLICABLE LAW OR REGULATION.

Nothing in these Legal Terms will be construed to obligate us to maintain and support the Services or to supply any corrections, updates, or releases in connection therewith.

15. Governing law

These Legal Terms and your use of the Services are governed by and construed in accordance with the laws of the State of California applicable to agreements made and to be entirely performed within the State of California, without regard to its conflict of law principles.

16. Dispute resolution

Informal Negotiations

To expedite resolution and control the cost of any dispute, controversy, or claim related to these Legal Terms (each a "Dispute" and collectively, the "Disputes") brought by either you or us (individually, a "Party" and collectively, the "Parties"), the Parties agree to first attempt to negotiate any Dispute (except those Disputes expressly provided below) informally for at least thirty (30) days before initiating arbitration. Such informal negotiations commence upon written notice from one Party to the other Party.

Binding Arbitration

If the Parties are unable to resolve a Dispute through informal negotiations, the Dispute (except those Disputes expressly excluded below) will be finally and exclusively resolved by binding arbitration. YOU UNDERSTAND THAT WITHOUT THIS PROVISION, YOU WOULD HAVE THE RIGHT TO SUE IN COURT AND HAVE A JURY TRIAL. The arbitration shall be commenced and conducted under the Commercial Arbitration Rules of the American Arbitration Association ("AAA") and, where appropriate, the AAA's Supplementary Procedures for Consumer Related Disputes ("AAA Consumer Rules"), both of which are available at the American Arbitration Association (AAA) website. Your arbitration fees and your share of arbitrator compensation shall be governed by the AAA Consumer Rules, where appropriate, limited by the AAA Consumer Rules. If such costs are determined by the arbitrator to be excessive, we will pay all arbitration fees and expenses. The arbitration may be conducted in person, through the submission of documents, by phone, or online. The arbitrator will make a decision in writing, but need not provide a statement of reasons unless requested by either Party. The arbitrator must follow applicable law, and any award may be challenged if the arbitrator fails to do so. Except where otherwise required by the applicable AAA rules or applicable law, the arbitration will take place in Yolo, California. Except as otherwise provided herein, the Parties may litigate in court to compel arbitration, stay proceedings pending arbitration, or to confirm, modify, vacate, or enter judgment on the award entered by the arbitrator.

If for any reason, a Dispute proceeds in court rather than arbitration, the Dispute shall be commenced or prosecuted in the state and federal courts located in Yolo, California, and the Parties hereby consent to, and waive all defenses of lack of personal jurisdiction, and forum non conveniens with respect to venue and jurisdiction in such state and federal courts. Application of the United Nations Convention on Contracts for the International Sale of Goods and the Uniform Computer Information Transaction Act (UCITA) are excluded from these Legal Terms.

In no event shall any Dispute brought by either Party related in any way to the Services be commenced more than one (1) years after the cause of action arose. If this provision is found to be illegal or unenforceable, then neither Party will elect to arbitrate any Dispute falling within that portion of this provision found to be illegal or unenforceable and such Dispute shall be decided by a court of competent jurisdiction within the courts listed for jurisdiction above, and the Parties agree to submit to the personal jurisdiction of that court.

Restrictions

The Parties agree that any arbitration shall be limited to the Dispute between the Parties individually. To the full extent permitted by law, (a) no arbitration shall be joined with any other proceeding; (b) there is no right or authority for any Dispute to be arbitrated on a class-action basis or to utilize class action procedures; and (c) there is no right or authority for any Dispute to be brought in a purported representative capacity on behalf of the general public or any other persons.

Exceptions to Informal Negotiations and Arbitration

The Parties agree that the following Disputes are not subject to the above provisions concerning informal negotiations binding arbitration: (a) any Disputes seeking to enforce or protect, or concerning the validity of, any of the intellectual property rights of a Party; (b) any Dispute related to, or arising from, allegations of theft, piracy, invasion of privacy, or unauthorized use; and (c) any claim for injunctive relief. If this provision is found to be illegal or unenforceable, then neither Party will elect to arbitrate any Dispute falling within that portion of this provision found to be illegal or unenforceable and such Dispute shall be decided by a court of competent jurisdiction within the courts listed for jurisdiction above, and the Parties agree to submit to the personal jurisdiction of that court.

17. Corrections

There may be information on the Services that contains typographical errors, inaccuracies, or omissions, including descriptions, pricing, availability, and various other information. We reserve the right to correct any errors, inaccuracies, or omissions and to change or update the information on the Services at any time, without prior notice.

AS WITH THE PURCHASE OF A PRODUCT OR SERVICE THROUGH ANY MEDIUM OR IN ANY ENVIRONMENT, YOU SHOULD USE YOUR BEST JUDGMENT AND EXERCISE CAUTION WHERE APPROPRIATE.

19. Limitations of liability

IN NO EVENT WILL WE OR OUR DIRECTORS, EMPLOYEES, OR AGENTS BE LIABLE TO YOU OR ANY THIRD PARTY FOR ANY DIRECT, INDIRECT, CONSEQUENTIAL, EXEMPLARY, INCIDENTAL, SPECIAL, OR PUNITIVE DAMAGES, INCLUDING LOST PROFIT, LOST REVENUE, LOSS OF DATA, OR OTHER DAMAGES ARISING FROM YOUR USE OF THE SERVICES, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, OUR LIABILITY TO YOU FOR ANY CAUSE WHATSOEVER AND REGARDLESS OF THE FORM OF THE ACTION, WILL AT ALL TIMES BE LIMITED TO THE LESSER OF THE AMOUNT PAID, IF ANY, BY YOU TO US DURING THE SIX (6) MONTH PERIOD PRIOR TO ANY CAUSE OF ACTION ARISING OR $100.00 USD. CERTAIN US STATE LAWS AND INTERNATIONAL LAWS DO NOT ALLOW LIMITATIONS ON IMPLIED WARRANTIES OR THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES. IF THESE LAWS APPLY TO YOU, SOME OR ALL OF THE ABOVE DISCLAIMERS OR LIMITATIONS MAY NOT APPLY TO YOU, AND YOU MAY HAVE ADDITIONAL RIGHTS.

20. Indemnification

You agree to defend, indemnify, and hold us harmless, including our subsidiaries, affiliates, and all of our respective officers, agents, partners, and employees, from and against any loss, damage, liability, claim, or demand, including reasonable attorneys' fees and expenses, made by any third party due to or arising out of: (1) your Contributions; (2) use of the Services; (3) breach of these Legal Terms; (4) any breach of your representations and warranties set forth in these Legal Terms; (5) your violation of the rights of a third party, including but not limited to intellectual property rights; or (6) any overt harmful act toward any other user of the Services with whom you connected via the Services. Notwithstanding the foregoing, we reserve the right, at your expense, to assume the exclusive defense and control of any matter for which you are required to indemnify us, and you agree to cooperate, at your expense, with our defense of such claims. We will use reasonable efforts to notify you of any such claim, action, or proceeding which is subject to this indemnification upon becoming aware of it.

22. Miscellaneous

Our failure to exercise or enforce any right or provision of these Legal Terms shall not operate as a waiver of such right or provision.

Privacy Policy

Last updated October 23, 2026

Who we are

We are Ryan Sieh ("Company," "we," "us," "our"), operating Osko from 2254 Cannery Loop, Davis, CA 95616. We operate the website https://osko.app (the "Site") and the mobile application Osko (the "App") (together, the "Services").

This Privacy Policy explains what we collect, why, who we share it with, and the controls you have. It is written to match what the code does. Questions or requests: support@osko.app.

By using the Services, you agree to this Privacy Policy. If you do not agree, do not use the Services.

1. What you give us

In the app: the tasks you type or say, the times you set, your name for Osko, the colour and pace you pick, and your answer to the age page. Pro cloud captures also send Apple's signed subscription record (see section 11). If you send feedback: the note you type, an email address if you choose to give one, and, if you leave "Include app details" on, the Osko version, the iOS version and the phone model. On the forum: the sign-in id Apple gives us for Osko, the display name you choose, and what you post or report.

2. What happens on your phone

Speech is turned into text on your phone by Apple's on-device recognition. Audio never leaves the phone. When a nudge fires, returns, or is marked Done, that happens on your phone and syncs through your own iCloud.

3. Splitting your words into tasks

When you speak a new nudge, the text of what you said is sent to our relay on Cloudflare, which forwards it to Anthropic's Claude through OpenRouter, in the United States, unless you chose "On-device only". The relay asks OpenRouter to use only providers that do not collect prompts and keep zero data retention. The text is used only to split it into tasks and is not stored by us. You can choose "On-device only" on the microphone screen, or turn on "Split on this phone only" in Settings → Nudges; then your words are split on your phone at your pauses and nothing is sent. Until you choose, no words leave your phone.

4. Nudges on your other devices

If you use Osko on more than one device, your phone sends the titles and times of changed tasks to our relay, which signs them and hands them to Apple Push Notification service for your other devices. The relay stores nothing: it keeps no token, no title and no payload.

5. Calendars

If you connect Apple Calendar, events are read on your device through Apple's framework and never sent to us. If you connect Google Calendar, Osko reads your calendar list and events with read-only scopes, on your device, and stores the signed-in account's email address on that device so it can show which account is connected. Osko's use of Google user data complies with the Google API Services User Data Policy, including the Limited Use requirements: the data is used only to show your events next to your nudges, is never transferred to others, and is never used for advertising. Disconnecting in Settings revokes the grant with Google and deletes the tokens from the device.

6. Technical data

To prove a request comes from the real Osko app, your phone sends Apple's App Attest key id; the relay keeps the id and a counter to refuse repeated requests, and limits requests by IP address and by key. Pro cloud captures also send Apple's signed subscription record (see section 11). Cloudflare, which runs the relay and the forum, logs requests for up to 7 days for abuse protection. The forum uses Cloudflare Turnstile to tell people from bots.

7. What we deliberately do not collect

No account for the app. No email for the app, unless you choose to give one when you send feedback. No analytics. No advertising identifiers. No audio. We cannot read your tasks: they live on your phone and in your private iCloud.

8. Public by default

Only the forum. Your display name and posts are public. Everything in the app is private to you.

9. How we use data

We use your tasks and times to fire nudges on your phone and your other devices. We use the forum sign-in id to keep your forum account yours, your display name to label your posts, and reports to moderate. We use request logs for abuse protection only. We use feedback to fix bugs and improve Osko, and the email address you give only to reply. We do not profile you, sell data, or use it for advertising.

10. Who we share with

Apple: iCloud holds your tasks under your own Apple account, we cannot read them; Apple Push Notification service carries nudges to your other devices; Apple processes Osko Pro purchases. Cloudflare runs the relay and the forum on our behalf, and carries feedback notes to our support inbox. OpenRouter and Anthropic receive the text of a spoken capture, in the United States, only to split it into tasks, unless you chose On-device only. Google receives your calendar requests when you connect Google Calendar. Nobody else receives your data. We disclose data only when the law requires it.

11. Payments

Purchases are made through Apple In-App Purchase. Apple handles your payment details; we never see your card number or your name. The app checks your subscription with Apple on your device. When a spoken capture is sent to our relay for splitting, the app sends Apple's signed record of your Osko Pro subscription with it, so the relay can confirm the subscription is active and count your use. The relay keeps that subscription's transaction id with its daily and monthly usage counts, and nothing else from the record. If you choose "On-device only" (Settings → Nudges → "Split on this phone only"), your words and the subscription record stay on your phone.

Changed October 23, 2026: this section now says the app sends Apple's signed subscription record with each cloud capture and the relay keeps usage counts per subscription. An earlier version said no receipt was sent to us; that was inaccurate from October 13, 2026.

12. Retention and deletion

Tasks stay on your phone and in your iCloud until you delete them or delete the app; Delete all data in Settings removes everything on the device, including calendar tokens and relay credentials, and revokes the Google grant. Request logs are kept for up to 7 days. The relay keeps one usage row per subscription while you use cloud splitting; it is deleted about three months after the last month you used it. Feedback emails stay in our support inbox until we delete them; write to support@osko.app to have yours deleted. Forum accounts and posts stay until you delete your account on the forum's "Me" page; deleting it removes your name and sign-in id and leaves your posts attributed to "deleted". For accounts deleted from now on, we keep only a one-way hash of the sign-in id, so that a ban can still close that Apple ID, for as long as the forum runs. Reports stay until resolved; a ban is kept so a closed account stays closed. Email support@osko.app to have a post removed.

13. Your rights

You can read, export and delete everything in the app from the app itself, because it lives on your device and in your iCloud. On the forum you can change your display name and delete your account at any time. If you live in a place with data-protection rights, such as the EU, the UK or California, you may also ask us to access, correct or erase data we hold, and to complain to your supervisory authority. Write to support@osko.app.

14. Children

The app asks your age once, right after the welcome screen, using Apple's Declared Age Range when available or a year of birth otherwise. Under 13, voice capture is off and nothing is ever sent to the relay for splitting; the app works fully with typed tasks. The forum requires you to be 13 or older. If you use Osko on more than one device, the titles and times of changed tasks still pass through our relay to reach your other devices (section 4); the relay stores none of them. The Send feedback screen is not shown to anyone under 13. We do not knowingly collect any other personal information from children under 13. If you believe a child has given us data, write to support@osko.app and we will delete it.

15. Where data lives

Your tasks live on your phone and in your private iCloud. Forum accounts, posts and reports, the relay's per-subscription usage counts, and the relay's per-device App Attest key ids (deleted about six months after last use) live in Cloudflare D1 in the United States. Text sent for splitting is processed in the United States and not stored. A feedback note is emailed to our support inbox and is not stored by the relay.

16. Feedback you send us

Settings → About → Send feedback sends us a note you type. It goes to our relay, which emails it to our support inbox through Cloudflare and keeps no copy. The email carries your note, the kind you picked (bug, idea or other), your email address if you gave one (we use it only to reply), and, if you leave "Include app details" on, the Osko version, the iOS version and the phone model. It never carries your tasks, lists, calendar, voice, name or age. To prove a note comes from the real app, the phone sends Apple's App Attest key id with it, and the relay limits how many notes one key can send (section 6).

17. Changes

When this policy changes, the "Last updated" date at the top changes with it. If a change affects what we collect or share, we will say so on this page for 30 days.
