Mochi Privacy Policy

Last updated: 13 November 2026

Mochi is a focus app for iPhone and iPad published by Predvix Limited ("we"). It uses Apple's Screen Time to guard the apps you choose until you finish what you set out to do. This policy explains what Mochi keeps on your device, what it sends and when, who handles it, for how long, and the choices you have. More about the app: predvix.com/mochi.

The short version

• No account and no sign-in. Mochi never asks for your name, email address or phone number.
• No ads, no analytics and no tracking. Mochi does not use the advertising identifier.
• Your Screen Time choices, sessions, stardust and sky stay on your device.
• A photo leaves your device only for a photo check, and only after you tap Agree on the notice Mochi shows before your first one. It goes to our server and to an AI service that checks it. We do not store your photos.
• Timed activities, reading reflections and daily routines send nothing about your activity.

What stays on your device

Mochi saves the apps and categories you chose to guard, your current and past session (the goal you typed, the activity type, the end time, your checklist and reflection), your stardust and stars, and the weekly sky. This data is kept in storage shared only between Mochi and its Screen Time extensions on your device. Other apps cannot read it, and we cannot see it.

Apple's Screen Time gives Mochi an encrypted token for each app you choose, not the app's name, so Mochi cannot tell which apps you guard. Uninstalling Mochi deletes the data above.

For a before-and-after photo check, Mochi keeps your starting photo on your device until that activity ends or is cancelled, then deletes it. It is excluded from your device's backups. Other photos are kept on your device only while they are being sent, and Mochi clears any leftovers when it next opens. Mochi uses the camera only when you take a photo for a check; it does not ask for access to your photo library.

What is sent for a photo check, and only if you agree

Homework, Tidy my space, Create something and Get ready are photo-checked activities: Mochi asks an AI service whether your photo shows the work done. Before your first photo check, Mochi shows a notice that names who receives your data. If you tap "Not now", or close the notice, nothing is sent and the activity does not start. If you tap "Agree", each photo check sends:

• the photo you take of your finished work, and for before-and-after activities your starting photo as well;
• the activity type and the goal you typed, the item list for Get ready, and the short code word Mochi asks you to show in the photo, which stops old photos from being reused;
• random identifiers for the activity and the attempt, which link a starting photo to its finished photo.

Anything visible in a photo is sent with it, so point the camera at your work, not at people or private documents. Mochi does not send your name, contact details, location, the apps you guard or your device's advertising identifier.

Our server checks that your agreement is recorded before it passes any photo on. You can withdraw it at any time on the Privacy & Plus screen in the app; after that, no photo is sent until you agree again. If we change which AI service checks photos, Mochi will show a new notice and ask again before sending anything to it.

Who processes it, and for how long

• Our server, hosted by Vercel Inc. Our server receives the photo check, passes it to the AI service and returns the result to your device. It holds your photos only in memory while the check runs and does not store them. Like every online service, Vercel processes your IP address and writes standard request logs (time, address and outcome, not your photos) to operate and secure the service. Its servers are in the United States.
• Vercel AI Gateway. Our server sends the photo check through Vercel's AI Gateway, which routes it to the AI model. Vercel states that the gateway does not retain prompts or outputs and deletes them as soon as each request completes.
• DeepSeek's model. The check itself is done by DeepSeek V4.1 Flash, an AI model made by DeepSeek. Our server tells the gateway to send photo checks only to DeepSeek's own service, never to another company that offers the model. DeepSeek's own terms and privacy policy decide how long it keeps photo checks and whether it uses them to train its models. DeepSeek states that it stores the data it processes on servers in the People's Republic of China.

An AI check can be wrong. No person looks at your photo before the result is shown, and we do not use your photos to train or improve any AI model.

Mochi Plus purchases

Mochi is free to use, and Mochi Plus is an optional auto-renewing subscription that adds more photo checks. Apple handles the payment under its own terms and privacy policy; we never see your name, Apple ID, card or payment details. To know whether Plus is active, Mochi and our server ask RevenueCat, Inc., a subscription service. RevenueCat receives a random purchase ID that the app creates (not linked to your name or Apple ID), your Mochi purchase and subscription history from Apple, and basic technical information such as your device model, iOS version, app version, country or region and IP address.

Our server keeps a few records under that random purchase ID, stored with Upstash, Inc., a database service: how many photo checks you have used, and which version of the photo-check notice you agreed to. They contain no photos and nothing that names you. Daily counts expire after a few days; the other records are deleted after 12 months without a photo check.

Uninstalling Mochi does not cancel a subscription. Manage or cancel Mochi Plus in your Apple ID settings, under Subscriptions. Refunds are handled by Apple.

Notifications

If you allow notifications, Mochi may show a reminder on your device that takes you back to your activity. These notifications are created on your device; we do not run a notification server and do not receive a notification token.

Sharing

We do not sell your information and we do not share it with advertisers or data brokers. The companies named above handle it only to provide their services to us. We may disclose information if the law requires it.

Transfers

Our server, Vercel, RevenueCat and Upstash operate in the United States, and DeepSeek in the People's Republic of China; each may process data in other countries where it runs. A photo check sends your data to the United States and to China.

Age

Mochi is intended for people aged 13 and over and is not directed at children under 13.

Your choices and rights

• Use Mochi without sending photos: choose Timed activity, Read & learn or Daily routine. They send nothing about your activity.
• Withdraw your agreement: on the Privacy & Plus screen. Photos already checked are handled as described above.
• Turn off Mochi's access: you can remove Mochi's Screen Time access at any time in your device's Settings.
• Delete what is on your device: uninstall Mochi.
• Records on our server: they are linked only to a random purchase ID, so we cannot look them up by name or email. If you have a question or a request, write to us below and we will do what we reasonably can.

Depending on where you live (for example the EU, the UK, California or Brazil), you may have rights to access, correct or delete personal data and to complain to your data protection authority.

Changes

If this policy changes, we will update this page and the date above. If a change affects who receives your photos, Mochi will also ask you again in the app before sending anything.
