Privacy Policy
Effective: May 27, 2026
This policy describes how the Snollo iOS application (App Store ID 6752620925) and the snollo.com website handle your information. Both are operated by Artsiom Pryshchepau.
At a glance
- Your sleep audio and sleep data live on your iPhone and in your own iCloud — under your Apple ID, across the Apple devices you sign into.
- A few third-party services receive limited data for crash reporting, subscription management, weather, and anonymous usage analytics. None of them sell your data, and none of them are advertising networks.
- The snollo.com website uses cookieless analytics — no cookies or local storage are set in your browser.
How we identify you
When iCloud is signed in on your device, Snollo uses your iCloud user identifier (CKUserRecordID) — a stable, app-scoped identifier provided by Apple — to associate your sleep data with your account. We never see your Apple ID, email address, or real-world identity.
If iCloud is not signed in, Snollo creates an anonymous local-only identifier on your device. Sleep data is not synced anywhere in this mode.
What we collect, and where it goes
Stored only in your private iCloud (Snollo cannot read these)
- Sleep sessions — duration, stages (Light/Deep/REM), heart rate, blood oxygen
- Audio recordings (snore clips, sleep sounds) — captured by your iPhone's microphone overnight, classified on-device by Apple's CoreML, saved as short clips you can play back
- Identified sounds — labels and timestamps for snoring, breathing, coughing, sleep talking, etc.
- Sleep health charts — aggregated weekly and monthly statistics
- Onboarding survey — answers you provided when first setting up the app
- Weather data — the weather we fetched alongside each sleep session
Stored in Apple's CloudKit public database (visible only to Snollo, not to other users)
- Profile — display name, sleep goal, bedtime reminder time, app permissions state (microphone, HealthKit, location, notifications), subscription state
- User ID — the CKUserRecordID linking your profile to your sleep data
These profile records are technically readable by Snollo through the CloudKit Dashboard. They are never displayed to other users, never sold, never shared with advertisers. Snollo has no social or discovery feature.
Read from / written to Apple HealthKit
With your permission, Snollo reads sleep data and motion data from HealthKit to power sleep-stage analysis, and writes your computed sleep score back to HealthKit so it appears alongside your other health metrics. This data is governed by Apple's HealthKit privacy rules.
Microphone
Your iPhone's microphone is used overnight (only after you tap "Start") to detect snoring, breathing, and other sounds. Audio is processed entirely on-device using Apple's CoreML framework. Only the resulting classifications and brief clips are saved — to your private iCloud — and only when sounds are detected.
Location
With your permission, Snollo briefly requests your device's coordinates and sends them to Apple's WeatherKit service to fetch local weather for your sleep timeline. The weather data is saved alongside your sleep session in your private iCloud. The coordinates themselves are not stored by Snollo.
Anonymous usage events
The Snollo iOS app reports anonymous events (which screens you visited, which features you used) to Mixpanel, PostHog, and TelemetryDeck so we can improve the app. These events are tied to your User ID for funnel analysis but contain no sleep data, no audio, no health information, and no name.
The snollo.com website uses PostHog in cookieless mode and Ahrefs Web Analytics: pageviews, scroll depth, and clicks are recorded, but no cookies or local storage are set in your browser, and visits cannot be linked to a returning person across sessions. Ahrefs Web Analytics is fully cookieless and does not store IP addresses or fingerprint visitors — it provides aggregate traffic and referrer data alongside our backlink dashboard. We also send Ahrefs a small set of named, anonymous UI events (e.g. App Store CTA clicks, deep-scroll milestones, and which currency region your visit detected) so we can build funnels alongside referrer data. These events contain no personal data, no IP address, and no cross-site identifier.
Crash and performance reports
When the app crashes or hits an error, Sentry and PostHog receive a stack trace, device model, OS version, and a non-identifying error context. Personally identifying information is stripped before transmission.
Subscription state
When you subscribe to Snollo Premium, RevenueCat receives your Apple receipt and links it to a pseudonymous identifier. This is required to validate your subscription, restore it on other devices, and manage cancellations. Apple itself handles payment — Snollo never sees your card or payment information.
Third-party services we use
- Apple iCloud / CloudKit — storage for sleep data, audio clips, and profile.
- Apple HealthKit — sleep stage analysis (read/write under your control).
- Apple WeatherKit — receives your coordinates briefly to return local weather. A native Apple service.
- Mixpanel — anonymous product analytics. Receives event names and your User ID; never sleep data, audio, or name.
- PostHog — anonymous product analytics (iOS) and crash reporting (iOS + web). The snollo.com website uses PostHog's cookieless mode.
- Ahrefs Web Analytics — cookieless website traffic analytics for snollo.com. Records anonymized pageviews, referrers, country-level geo, and a small set of named UI events (App Store CTA clicks, deep-scroll milestones, detected currency region). No cookies, no local storage, no IP retention, no fingerprinting.
- TelemetryDeck — privacy-focused aggregate analytics for iOS. Hashed identifiers, no IP retention.
- Sentry — iOS crash and error reporting. PII is stripped from events before transmission.
- RevenueCat — subscription validation and restoration.
Each service operates under its own privacy policy. None of these services are used for advertising, none of them combine Snollo's data with other companies' data for cross-app tracking, and none of them are data brokers. We have no data-selling relationships with anyone.
Your rights
If you are in the EU, UK, EEA, Switzerland, California, or any jurisdiction granting equivalent rights, you have the right to:
- Access the personal data Snollo holds about you
- Correct any inaccurate data
- Delete your profile and associated data
- Receive a copy of your data in a portable format
- Object to or restrict processing
- Withdraw consent at any time
To exercise any of these rights:
- Delete your profile from within Snollo's settings — this removes your record from CloudKit immediately.
- Uninstall the app — your private CloudKit data becomes inaccessible from your device, and Apple's standard retention rules apply to iCloud-stored data.
- Email support@snollo.com for any other request — including data export, analytics-event purge requests to our processors, or specific concerns. We respond within 30 days.
California (CCPA / CPRA): Snollo does not sell or share your personal data for cross-context behavioral advertising. To confirm this in writing or to exercise any CCPA right, contact support@snollo.com.
Children's privacy
Snollo's App Store age rating is 12+. The app is not directed to children under 12 and we do not knowingly collect personal data from anyone under 12. If you are a parent or guardian and believe a child under 12 has used Snollo, please contact support@snollo.com and we will delete the relevant profile and CloudKit records.
Data retention
- Sleep sessions, audio clips, sleep charts, onboarding answers, profile — retained in your iCloud until you delete the app or your profile.
- Anonymous analytics events (Mixpanel, PostHog, TelemetryDeck) — retained per each processor's default policy, typically 12 months.
- Anonymized website analytics (Ahrefs Web Analytics) — aggregate pageview, referrer, geo, and named-event data retained for up to 12 months. No cookies, no IP addresses, no identifiers persisted.
- Crash and error reports (Sentry, PostHog) — retained for up to 90 days.
- Subscription data (RevenueCat) — retained for as long as Snollo is operational, for purchase-restoration purposes.
Security
Sleep data lives in your private iCloud container, encrypted by Apple. Snollo cannot read it from any server or dashboard. Profile data in Apple's CloudKit public database is protected by Apple's standard CloudKit security. Network traffic between the app and any third-party service is encrypted in transit (TLS).
Snollo does not operate a backend database for user sleep data — it lives in your own iCloud, under your Apple ID. Anonymous analytics and third-party services (listed above) are the only places Snollo-side data exists.
Changes to this policy
We will update this policy whenever data flows change — for example, when we add, remove, or change a third-party service or processing purpose. The effective date at the top of the page reflects the most recent revision. Continued use of Snollo after a revision constitutes acceptance of the updated policy.
