Privacy Policy
Effective date: October 1, 2026
Sieva is built so that your screenshots, and everything Sieva learns from them, stay yours. They live on your device and, if you choose, in your own iCloud account. We cannot see them, or any personally identifiable data about you. This policy explains the small amount of information we do handle, and how to turn off the one optional piece.
Sieva is still in development. This policy covers this website today and the app as it will ship; we will update it if anything changes before launch.
Your screenshots and what Sieva extracts from them
Sieva reads screenshots you choose to import, pulls out text and details, and organizes them. That processing happens on your iPhone. The images, the extracted text and fields, your notes, reminders, stacks, and search history are stored on your device or in your personal iCloud account, which we have no access to. They are never sent to us.
On iPhone, Automatic uses Apple’s Private Cloud Compute when available, sending screenshots, your searches and questions, and relevant text to Apple for private processing. It falls back to on-device processing. Choose Built-in Brain in Settings to keep analysis on your iPhone. Private Cloud runs under Apple’s privacy terms. We do not receive anything from it. Apple describes the guarantees Private Cloud Compute makes about user data in its security research post:
We designed Private Cloud Compute to make several guarantees about the way it handles user data:
- A user’s device sends data to PCC for the sole, exclusive purpose of fulfilling the user’s inference request. PCC uses that data only to perform the operations requested by the user.
- User data stays on the PCC nodes that are processing the request only until the response is returned. PCC deletes the user’s data after fulfilling the request, and no user data is retained in any form after the response is returned.
- User data is never available to Apple — even to staff with administrative access to the production service or hardware.

Information we do not collect
Personal information. Sieva has no accounts. The app never asks for your name, email address, or any other personal detail.
Your content. No screenshots, extracted text, notes, search terms, or locations leave your device to reach us.
Ads or third-party tracking. Sieva contains no ads and no advertising or tracking SDKs.
Third-party analytics. The app uses no outside analytics or crash-reporting service. See the next section for what we do collect ourselves, and “The waitlist on this website” for the website.
Anonymous usage and performance metrics via MetricKit
To understand how Sieva performs in the real world and which parts of it people actually use, the app can send us anonymous metrics collected with Apple’s MetricKit framework, the same privacy-preserving system iOS uses to report app performance. You choose whether to share them when you first install the app, and you can change that choice at any time in Settings inside Sieva.
What the metrics contain:
- Counts and durations: which screens you use and for how long, how long processing takes, how often features are used, and how big your library is. Anything that could be revealing is reported as a broad bucket rather than an exact number. For example:
- Library size is one of 0, 1–99, 100–999, 1,000–9,999, or 10,000+.
- Cleanup batch sizes are bucketed the same way.
- Private Cloud usage is a band such as “ok”, “approaching limit”, or “limit reached”, never a request count tied to you.
- Performance and stability: launch time, hangs, memory, and crash diagnostics, attributed to which screen or task was active.
- Device model, iOS version, app version, language, App Store country, which plan you’re on, and a random install identifier.
What they never contain:
- Screenshots, extracted text or fields, notes, search terms, or the names of anything you created.
- Your name, email, Apple ID, iCloud identifiers, or hardware identifiers.
- Your location, IP address, or any other network identifier.
- Any other metadata that could be used to personally identify you.
The install identifier is a random number created when Sieva is first installed. It is not linked to you or your device, and it is deleted when you turn metrics off; turning them back on creates a new one. Metrics are sent to servers we operate on Cloudflare and are used only to fix bugs and improve the app. They are not shared or sold.
Crash reports through Apple
Separately, if you have opted in to sharing analytics with app developers in iOS Settings under Privacy & Security, Apple may send us standard crash and diagnostic reports for Sieva. These contain no personal information or device identifiers. You can turn that off in the same iOS setting.
Photos access
Sieva asks for access to your Photos library only to import the screenshots you select, and later, if you choose, to delete the originals it has already saved. Deletion never happens silently: you review each batch, confirm it, and the items go to Recently Deleted in Photos where they can be recovered for 30 days.
iCloud
Sieva uses iCloud for syncing, with all synced data securely stored in your iCloud account. Sync is optional, it uses your own private iCloud database, and we cannot read what is in it.
The waitlist on this website
If you join the waitlist we store your first name, your email address, whether you ticked the beta-testing box, and when you signed up. We use that to send one email when Sieva launches and, if you asked, TestFlight invitations. We don’t sell it, share it, or add you to anything else. To be removed, reply to any email we send or write to us at the address below and we will delete the record.
To see how many people visit and how they found us, this website may use privacy-first web analytics, such as Cloudflare Web Analytics. If it does, it only counts visits: the page, the site that linked to it, your country, and your browser and device type, reported to us in aggregate. It sets no cookies, stores nothing on your device, does not fingerprint you, and does not follow you to other sites. We will never use advertising or cross-site tracking on this website. The website is served by Cloudflare, which keeps the ordinary short-lived request logs any host does.
Support requests
If you contact us through the support form, we store your first name, email address, the topic, your message, and any device details or screenshots you choose to add. We keep them in our own database on Cloudflare and file them in Linear, the issue tracker we use to answer and follow up; screenshots are stored in Linear only. We use them to reply and to fix what you report, nothing else. To have a request removed, write to us at the address below.
When you write from inside the app with usage sharing on, the form offers to include your install identifier, checked by default. If you leave it checked, we can look up the usage and crash reports from your install to help with your request, which links those reports to your email for that purpose. Uncheck it and the identifier is not sent.
The form uses Cloudflare Turnstile to keep out bots. It checks your browser without cookies for tracking or advertising and without asking you to solve puzzles; see Cloudflare’s Turnstile privacy addendum.
Videos on this website
Some guides include videos hosted on YouTube. Until you press play, a video is only a picture served from sieva.app, and your browser does not contact YouTube or Google. When you press play, the video loads from YouTube’s privacy-enhanced mode (youtube-nocookie.com), andGoogle’s privacy policy applies to it.
Data storage and security
Everything Sieva creates is stored on your device and, when sync is on, in your iCloud account. Files on the device are protected by iOS data protection. See Apple’s Privacy Policy for details on how iCloud handles data.
Third-party services
Sieva does not integrate with or share data with third-party services, apart from Apple’s App Store for purchases. When you buy a subscription or unlock, we receive confirmation of the purchase from Apple, not your payment details. If you email us or use the support form, we use your details only to reply, as described under Support requests.
Children’s privacy
Sieva does not knowingly collect personal information from anyone, including children under 13. The anonymous metrics described above contain nothing that identifies a person.
Changes to this policy
We may update this policy to reflect changes in the app or for legal or operational reasons. Updates are posted on this page with a new effective date.
