1. Optional readings and moments

Heart rate. If you choose to allow it, the app requests read access to heart-rate samples in Apple Health through HealthKit. It never writes Health records. It can read samples available during a session and a recent reference for comparison. A fresh-reference step reads only new samples for up to 210 seconds, can finish earlier when enough data is available, and can be skipped. Insufficient reference data produces no comparison. The optional “Last 15 minutes” feature reads the previous 30 minutes, dividing those readings into the period you review and the earlier reference period.

The app does not start a workout or force continuous optical-sensor recording. It does not keep a background sensor session running. Some sessions may have few or no readings; unavailable readings are not invented.

Motion. If enabled, the app uses accelerometer readings during the session to make a simple movement summary. The saved summary contains a sample count and average magnitude, not a raw motion recording. Movement does not establish a reason for a pulse change.

Moments you mark. You can answer or skip Hot Seat questions and mark a bluff, tension, or another moment yourself. These are your reports, not detected facts. The app does not record spoken answers, audio, video, or location.

Truth or bluff. This separate guessing game uses no sensors. The storyteller declares truth or bluff, a friend guesses, and the app reveals the storyteller’s selection. Those choices stay only in memory for the current game; they are not saved to history or a recovery checkpoint. A reveal is not verification of what someone said.

2. What stays on your Watch

The app stores up to 30 recent rounds in its local history. Depending on the features you use, a saved round can include:

• Session dates and duration, heart-rate values and sample dates, source sample identifiers, and the reference readings used for comparison.
• A movement summary, answered-question count, and manually marked moments with their timing and question positions.
• The app’s question prompts, their displayed intervals, and each saved question’s answered, skipped or unfinished status. These are catalog prompts and completion choices, not recordings of your spoken answers.
• The selected wearer and mode, descriptive status notes such as observed collection errors, limits or Low Power Mode, and available start/end battery information.

The history directory is excluded from device backup. The app applies the operating system’s file protection to saved history. No app cloud account, server upload, or iPhone companion transfer is used in this Watch-only release.

Interrupted-session recovery. The app keeps one bounded local checkpoint of an active session, updated after marked moments or completed questions and periodically while the session is active. It contains the same kinds of session information described above and uses the history directory’s file protection and backup exclusion. If the app stops unexpectedly, a recovered session ends at the last successful checkpoint. Missing time and readings are not filled in. Saving that session to history clears its matching checkpoint; the saved round retains the same identity to avoid duplicates.

Guest context. Guest sessions exclude the usual wearer’s recent history and offer an optional fresh reference. Without enough fresh readings, comparison stays unavailable. To reduce mixing readings from different people, the app stores a small separate guest-use timestamp or an indication that the Watch has not yet been confirmed back with its usual wearer. Recent guest use temporarily blocks historical comparisons and lookback. This marker remains when you clear history; removing the app removes its local app data.

Wearer choices are supplied by you. The app does not identify a person or verify who is wearing the Watch.

Appearance preferences. The app also remembers Nubi’s body color, outfit, hairstyle, makeup, and accessory, along with your app accent, interface theme, and character-motion setting, in local system preferences on your Watch. These choices do not require Health access and are not sent to Sun Ryse. They are separate from saved rounds and remain when you clear history. The history directory’s backup exclusion applies to saved rounds, not these system preferences.

Recent questions. Local system preferences remember a bounded list of recent catalog question numbers for each deck to reduce repetition. This list contains no answers, player names, timestamps, truth or bluff choices, or readings. It remains when you clear round history, and is removed with the app’s local data. The history directory’s backup exclusion does not apply to system preferences.

3. Sharing is your choice

You can preview a Nubi invitation image or a short text message, then choose to share it through the operating system’s share sheet. The image shows your chosen Nubi appearance. Both formats contain game counts: for a session, the number of questions answered or moments marked and counts of bluffs and tense moments you labeled yourself; for Truth or bluff, only the number of stories revealed. The image is rendered locally, without uploading it to Sun Ryse.

Invitations do not contain heart-rate readings, dates, player names, question text, private answers, or individual truth or bluff selections. They identify labels as personal reports and reveals as player-declared choices, not detected lies. No invitation is sent automatically. Only the image or text you choose is handed to the destination you select, whose privacy practices apply.

We do not sell app data, use HealthKit data for advertising, or send it to analytics or external AI services.

4. Your controls and deletion

• Use the app without readings. Heart-rate and motion features are optional and can both be switched off. “Play now” starts Hot Seat without sensor permissions, and Truth or bluff never uses sensors.
• Change Health access. Use Apple’s Health or Privacy settings to change the app’s permission. Previously saved app rounds remain until you delete them.
• Delete a round or clear history. Use Recent rounds in the app. This removes the app’s saved rounds, not the original samples in Apple Health. The separate guest-use marker, appearance preferences, recent question numbers and any separate recovery checkpoint remain.
• Review or discard a checkpoint. Use “Review recovered session” on Home to save it to history and review its contents. You can then delete it from Recent rounds, or explicitly discard the checkpoint from Home instead. A recovered session retains its last checkpoint time.
• Remove all local app data. Delete the app from your Watch. This does not delete Apple Health records or an invitation you already shared with someone.

Character motion. You can turn it off in “Make it yours.” The app also respects the Watch’s Reduce Motion setting. Nubi’s short reactions follow app interactions; they are not an analysis of your health or a classification of your mood.

Because saved readings and rounds are local, Sun Ryse cannot retrieve or delete them remotely. You can contact us about information you have voluntarily sent to support.

5. This website and support email

This website is separate from the Watch app. It is a static site hosted by Cloudflare Pages. We have added no analytics, advertising, tracking pixels, external fonts, cookies, or contact forms. Cloudflare processes network request information, such as IP addresses and request metadata, to deliver and protect the website. See Cloudflare’s privacy policy for its practices.

If you email support, we and our email service providers receive the information you send, including your email address and message. We use it to respond and handle the issue. Please leave out health readings and private answers unless they are necessary to explain the issue. Support email is not part of the app’s local-only storage.

We keep support correspondence as needed to handle the request, maintain relevant business records, or meet legal obligations. Contact us to request access to or deletion of information you sent us, subject to those obligations. We do not add support senders to a marketing list automatically.

6. Changes and contact

We will update this page and its date if these practices change. This policy describes the Watch-only app available on the App Store.
