The fine print

Privacy Policy.

A plain-English explanation of how Rhevio handles your information. The short version: we run no servers and never see your data. With Premium you can turn on iCloud sync, which keeps it in your own private iCloud account.

Effective August 20, 2026

SOLARTUNE d.o.o. ("SOLARTUNE," "we," "us," or "our") operates the Rhevio mobile application ("Rhevio" or the "App"). This Privacy Policy explains how we handle information in connection with your use of Rhevio.

Rhevio is built on a privacy-first principle: we do not operate servers that store your personal information and we do not require accounts. Your content is stored on your device, and, if you have Premium and turn on iCloud Sync, in your own private iCloud database so it can appear on your other devices. SOLARTUNE cannot see it either way. We collect anonymous product analytics to improve the App, but we never build personal profiles or track you across apps or websites.

01Personally Identifiable Information We Do Not Collect

Rhevio does not collect, transmit, or store any personally identifiable information, including:

  • Email addresses, names, or user accounts - Rhevio requires no sign-up or authentication of any kind.
  • Advertising identifiers (IDFA) - Rhevio contains no advertising and does not access the Identifier for Advertisers.
  • Device fingerprints or cross-app tracking data.
  • Contacts, photos, calendar, or camera data.

02Information You Create in the App

All content you create in Rhevio is stored on your device using Apple's SwiftData framework and is never transmitted to SOLARTUNE or any third party. This includes:

  • Tasks and their attributes (titles, notes, checklist steps, due dates, priorities, energy levels, tags)
  • Routines and routine schedules
  • Mood check-ins and end-of-day reflections
  • Saved locations used for location-based automation, including any workout activity you tag a place with
  • Records of time spent at a saved place, used to log workouts and complete place-tied tasks
  • App settings and preferences
  • Focus session history and scores

This data exists within the App's sandboxed storage on your device and, if you have enabled iCloud Sync, in your private iCloud database as described in the next section. We have no ability to access, read, or recover it in either case.

03iCloud Sync

Rhevio offers optional iCloud Sync as a premium feature. When it is turned on, the content listed in the previous section is also stored in your private iCloud database (Apple's CloudKit private database) so that it can appear on your other devices signed into the same Apple account.

  • This data lives in your own Apple account, under Apple's privacy terms, not on any SOLARTUNE server.
  • SOLARTUNE has no access to it, cannot read it, and cannot recover it.
  • Rhevio uses only the private CloudKit database. It never writes your content to a public or shared database.
  • Sync is a Premium feature and can be turned off at any time under Settings in the App. With sync off, Rhevio works exactly as before with everything stored on your device only.
  • Records of time spent at a place are tagged with a random per-install identifier so that each device only acts on its own sessions. That identifier is generated on your device, is not linked to you or your Apple account, and is never sent to SOLARTUNE.

For information about how Apple handles iCloud data, see Apple's Privacy Policy.

04Apple Health (HealthKit)

If you tag a saved place with an activity, Rhevio can record the time you spend there as a workout in Apple Health. This is optional and off unless you set up a place this way.

  • Write access is used solely to save those workouts to Apple Health.
  • Read access is used solely to check for workouts already recorded by another device, such as an Apple Watch, so that Rhevio does not save a duplicate.

Health data is used only for these purposes. It is never sent to SOLARTUNE, never used for advertising or marketing, never shared with or sold to any third party, and is never included in crash reports or product analytics. Rhevio does not use health data for any purpose other than the workout logging described here. You may deny or revoke Health access at any time in iOS Settings, and Rhevio continues to work without it.

05Device Permissions

Rhevio may request the following device permissions. None of them send data to SOLARTUNE:

(a) Location (CoreLocation). Rhevio uses location data to trigger task reminders and routine suggestions when you arrive at or leave saved locations (geofencing), and to time workouts at places you have tagged with an activity. Your live position is evaluated on your device and is never transmitted to SOLARTUNE. The places you save, including their names and coordinates, are stored like the rest of your content: on your device, and in your private iCloud database if you have iCloud Sync turned on. Rhevio may request "Always" location permission to enable geofencing while the App is in the background. You may deny or revoke this permission at any time in iOS Settings.

(b) Apple Maps (MapKit). While you are adding or editing a saved place, Rhevio uses Apple's Maps services to search for an address and to look up the address of a point you pick on the map. The text you type and the coordinates you select are handled by Apple for that lookup, under Apple's Privacy Policy. This happens only while you are setting up a place, never in the background and never as part of geofencing, and SOLARTUNE receives none of it.

(c) Microphone and Speech Recognition. Rhevio offers voice-to-text task creation using Apple's on-device speech recognition (SFSpeechRecognizer with on-device recognition required). Audio is processed locally and is never sent to SOLARTUNE, Apple servers, or any third party. You may deny or revoke this permission at any time in iOS Settings.

(d) Notifications. Rhevio uses local push notifications to deliver task reminders, routine nudges, focus session alerts, reminders tied to arriving at or leaving a saved place, and prompts to start or finish a workout at a place you have tagged with an activity. These notifications are generated and scheduled entirely on your device. No notification data is sent to SOLARTUNE. You may disable notifications at any time in iOS Settings.

(e) Apple Health (HealthKit). Rhevio requests permission to save workouts to Apple Health, and to read workouts so it does not duplicate a session already recorded by another device. See the Apple Health section above for the full description. You may deny or revoke this permission at any time in iOS Settings.

06Crash Reporting

Rhevio uses Sentry (provided by Functional Software, Inc.) for crash reporting in production builds only. The purpose of crash reporting is solely to identify and fix technical errors that affect App stability.

What Sentry receives:

  • Technical crash data: stack traces, error messages, device model, iOS version, App version, and available memory at the time of a crash.
  • Short technical breadcrumbs describing what the App was doing before an error, using fixed labels such as "iCloud sync attempt failed" or "workout save retried". They never contain your content.
  • Basic session health data: when an app session started, how long it lasted, and whether it ended in a crash.
  • A randomly generated event identifier.

What Sentry does not receive:

  • No personally identifiable information (PII). The Sentry SDK is configured with sendDefaultPii disabled.
  • No task content, routine data, mood entries, reflections, locations, health or workout data, or any other user-created content.
  • No device identifiers, advertising identifiers, or account information.

Rhevio also samples 20% of app sessions for performance traces, which measure how long technical operations take. Traces contain timing and technical identifiers only, never your content. Sentry processes this data as a data processor on our behalf. For Sentry's own privacy practices, see sentry.io/privacy.

Opt-out: Rhevio does not currently provide an in-app toggle for crash reporting. Because crash reports require an internet connection to transmit, you can effectively prevent crash reporting by using Rhevio in airplane mode or by revoking the App's internet access through a device-level firewall or configuration profile.

07Product Analytics

Rhevio uses PostHog (provided by PostHog Inc.) for anonymous product analytics. The purpose of analytics is solely to understand how the App is used so we can improve it. Analytics data is processed on PostHog's European Union servers (eu.i.posthog.com).

What PostHog receives:

  • Anonymous usage events: screens viewed, features used (e.g., task created, task completed, routine spawned), onboarding progress, and subscription-related events (paywall viewed, purchase started/completed).
  • Basic device metadata: device model, iOS version, App version.
  • Anonymous session data: session start/end times and duration.
  • A randomly generated anonymous identifier (not linked to your Apple ID or any personal identity).

What PostHog does not receive:

  • No task titles, notes, or content of any kind.
  • No reflection text, routine names, or mood check-in details.
  • No location names or coordinates.
  • No health or workout data of any kind.
  • No email addresses, Apple ID, or any account information.
  • No advertising identifiers (IDFA) or cross-app tracking data.

Analytics events are not collected in development builds of the App. For PostHog's own privacy practices, see posthog.com/privacy.

Opt-out: You can disable product analytics at any time by turning off the "Share Analytics" toggle in the App's Settings. This immediately stops all analytics event transmission. Analytics are enabled by default.

08In-App Purchases and Subscriptions

Rhevio offers optional premium subscriptions (monthly and yearly) through Apple's App Store. All billing, payment processing, and subscription management is handled entirely by Apple.

SOLARTUNE does not collect, process, or have access to your payment information, credit card details, Apple ID, or billing address. For information about how Apple handles your purchase data, see Apple's Privacy Policy.

09Task Sharing

Rhevio allows you to share tasks with others via universal links. When you share a task:

  • The task data (title, notes, due date, and other task attributes) is encoded directly into the URL as a base64url-encoded parameter.
  • No data is sent to or stored on any server. The shared information exists solely within the URL itself.
  • Anyone who receives the URL can decode and view the task data contained in it.

You should exercise discretion when sharing task links, as the task content is embedded in the URL in an encoded (not encrypted) format.

10Children's Privacy

Rhevio is rated 9+ on the Apple App Store. Rhevio does not knowingly collect personal information from anyone, including children under the age of 13 (or the applicable age in your jurisdiction). Because Rhevio does not collect personal data from any user, there is no personal data from children to identify or delete.

If you are a parent or guardian and believe your child has somehow provided personal information through the App, please contact us at support@rhevio.app and we will investigate promptly.

11Your Rights Under the General Data Protection Regulation (GDPR)

If you are located in the European Economic Area (EEA), the United Kingdom, or Switzerland, the following applies:

(a) Data Controller. SOLARTUNE d.o.o., a company organized under the laws of the Republic of Slovenia, is the data controller for any personal data processed through the App.

(b) Legal Basis. The limited personal data processing that occurs (crash reporting via Sentry and anonymous product analytics via PostHog) is based on our legitimate interest in maintaining the stability, security, and quality of the App (Article 6(1)(f) GDPR). We have assessed that this interest is not overridden by your rights, given that no PII is included in crash reports or analytics events and the processing is minimal and technical in nature. You may opt out of product analytics at any time via the "Share Analytics" toggle in the App's Settings.

(c) Data Subject Rights. You have the right to:

  • Request access to personal data we hold about you;
  • Request rectification or erasure of your personal data;
  • Object to or request restriction of processing;
  • Data portability;
  • Lodge a complaint with your local supervisory authority.

In practice, because we do not collect PII and crash reports contain no information that could identify you, we are unable to associate any crash report data with a specific individual. All user-created content is stored on your device and, where you have enabled iCloud Sync, in your own private iCloud database. It is under your sole control in both cases.

(d) Sub-processors. Sentry (Functional Software, Inc., San Francisco, CA, USA) acts as a data processor for crash reporting. PostHog (PostHog Inc., San Francisco, CA, USA) acts as a data processor for product analytics; analytics data is processed on PostHog's EU servers. Apple Inc. acts as a processor for iCloud Sync, storing your content in your own private iCloud database on Apple's infrastructure. Data transfers to the United States are covered by the EU-US Data Privacy Framework and each processor's data processing agreement.

(e) Contact for Data Protection Inquiries. SOLARTUNE d.o.o., support@rhevio.app.

12Your Rights Under the California Consumer Privacy Act (CCPA/CPRA)

If you are a California resident:

  • We do not sell your personal information as defined by the CCPA/CPRA.
  • We do not share your personal information for cross-context behavioral advertising.
  • We do not use or disclose sensitive personal information for purposes beyond those permitted under the CPRA.
  • We do not engage in profiling in furtherance of decisions that produce legal or similarly significant effects.
  • Because Rhevio does not collect personal information that identifies you, most CCPA/CPRA rights (access, deletion, correction, opt-out of sale) are not practically applicable. Nevertheless, you may contact us at support@rhevio.app with any privacy-related requests.

13Your Rights Under the Personal Information Protection and Electronic Documents Act (PIPEDA)

If you are a Canadian resident, SOLARTUNE is committed to compliance with PIPEDA. Because Rhevio does not collect, use, or disclose personal information that identifies you, the data protection principles of PIPEDA - including consent, limiting collection, and accountability - are satisfied by design. Should you have questions or concerns, you may contact us at support@rhevio.app or file a complaint with the Office of the Privacy Commissioner of Canada.

14Data Retention and Deletion

(a) Your content. All user-created content is stored on your device, and in your private iCloud database if you have enabled iCloud Sync. You control this data entirely. You may delete individual items within the App at any time.

Uninstalling Rhevio removes all App data from that device. If iCloud Sync was turned on, a copy remains in your private iCloud database and will return if you reinstall the App on a device signed into the same Apple account. To delete that copy, open iOS Settings, tap your name, then iCloud, then Manage Account Storage, and remove Rhevio's data. You can also turn iCloud Sync off in the App before uninstalling.

(b) Crash reports. Crash data transmitted to Sentry is retained according to Sentry's data retention policies. Because crash reports contain no PII, this data cannot be linked to you. For details on Sentry's retention periods, see sentry.io/privacy.

(c) Analytics data. Anonymous analytics data transmitted to PostHog is retained according to PostHog's data retention policies. Because analytics events contain no PII, this data cannot be linked to you. For details, see posthog.com/privacy.

(d) Apple. Apple may retain purchase and subscription records in accordance with Apple's Privacy Policy. SOLARTUNE has no control over or access to this data.

15Security

Your on-device data benefits from the security features built into iOS, including file system encryption and the App sandbox. Content synced through iCloud is encrypted in transit and at rest by Apple, and is stored only in your private CloudKit database. Crash reports transmitted to Sentry are sent over HTTPS (TLS encryption in transit). We do not operate any servers that store your data.

While no method of electronic transmission is 100% secure, we believe the privacy-by-design architecture of Rhevio - where your data stays on your device or inside your own Apple account, and never reaches us - provides strong protection for your information.

16International Data Transfers

Crash report data may be transferred to and processed in the United States by Sentry. Analytics data is processed on PostHog's European Union servers and remains within the EU. If you enable iCloud Sync, the storage location of your iCloud data is determined by Apple and governed by Apple's privacy policy and terms, not by SOLARTUNE. SOLARTUNE ensures that appropriate safeguards are in place for any international transfers in compliance with applicable data protection laws, including the EU-US Data Privacy Framework.

17Changes to This Privacy Policy

We may update this Privacy Policy from time to time, for example when the App gains a feature that handles information differently. The current version is always published at rhevio.app/privacy and linked from the App's Settings. A revised policy takes effect on the "Effective Date" shown at the top of this document, which is normally the day we publish it.

Where a change materially reduces the protection of information we already hold about you, or where applicable law requires it, we will give you notice before the change takes effect and, where consent is required, ask for it. Your continued use of Rhevio after the effective date of a revised policy constitutes your acceptance of the changes.
