Privacy Policy | Ryft Calc — How We Protect Your Data

1) Information We Process

1.0 Definitions

"Personal information" means information that identifies, relates to, describes, is reasonably capable of being associated with, or could reasonably be linked (directly or indirectly) with a particular person or device. Some data you enter into the App may be personal information depending on content.

1.1 Information you provide in the App

The App processes content you enter, such as calculations (expressions), results, history items (including optional comments), templates (names, expressions, categories, optional descriptions), and session metadata (for example names and colors).

This content is primarily stored locally on your device and is used to provide App features. We do not require you to provide your name, email address, or other account identifiers to use core features.

1.2 Local app data (preferences and state)

The App stores settings and state on your device, such as theme/UI preferences, accessibility-related settings, keypad layout customization, per-session calculator state, plugin selections and plugin-related preferences, and tutorial/showcase progress.

1.3 Purchases and subscriptions

If you purchase premium features on supported platforms, the App interacts with the platform billing system (for example Apple App Store / Google Play) and may also interact with a purchase verification/entitlements server when configured. These interactions may involve transmitting purchase metadata needed to validate or restore access (for example product identifiers, transaction identifiers, and purchase tokens).

1.4 Anonymous device identifier (for entitlements)

To support premium access and purchase restoration, the App may generate and store an anonymous device identifier (a random UUID-like value). When premium features are used, this identifier may be used with billing/entitlements providers (for example as an app user id) and/or transmitted to a verification server if configured.

1.5 Import/export and files you choose

The App offers optional import/export features (for example exporting history, importing from a file, or sharing templates via QR/text). When you use these features, the data is read from or written to file locations you choose, and the App may request OS permissions required for the operation.

1.6 Sharing via system features

If you choose to share content via system sharing features, the App passes the selected content to your device's operating system and the recipients you choose.

1.7 Information we do not intentionally collect

The App is designed to operate without collecting sensitive personal information such as government identifiers, precise geolocation, or biometric data. Please do not enter sensitive personal information into free-form fields. If you do, you do so at your own risk.

1.8 Support communications

If you contact us (for example by email), we will process the information you provide (such as your email address and the contents of your message) to respond and provide support. We may retain support communications for recordkeeping and to improve support quality.

2) Legal Basis for Processing (GDPR)

If you are located in the European Economic Area (EEA), UK, or Switzerland, we process your personal information based on the following legal grounds under the General Data Protection Regulation (GDPR):

Contractual necessity (Art. 6(1)(b) GDPR): Processing is necessary to provide the App's core features, enable premium purchases, and restore entitlements.
Legitimate interests (Art. 6(1)(f) GDPR): We have a legitimate interest in preventing fraud, abuse, and unauthorized circumvention of premium restrictions, improving the App, and providing support communications.
Consent (Art. 6(1)(a) GDPR): Where required, we obtain your consent for specific data processing activities (for example, if we introduce analytics or optional features requiring consent in the future).
Legal obligation (Art. 6(1)(c) GDPR): We may process data to comply with legal requirements, such as responding to valid legal requests.

You have the right to object to processing based on legitimate interests. See Section 8 (Your Privacy Rights) below.

3) How We Use Information

To provide, operate, maintain, and improve the App.
To store your preferences and state on-device.
To enable, validate, and restore premium access and purchases.
To support import/export and sharing when you request them.
To prevent fraud, abuse, and misuse (for example attempts to bypass premium restrictions), where applicable.

We do not sell, rent, or trade your personal information. We may share limited information with the following third parties:

Platform providers (Data Processors): Apple Inc. and Google LLC process purchase transactions on their respective platforms. See Apple Privacy Policy and Google Privacy Policy.
Purchase verification server (Data Processor): When configured, our entitlements verification server processes anonymous device identifiers and purchase metadata to validate entitlements. Data may be transferred to the United States.
When you export/share: Content is shared to file destinations or recipients you explicitly choose via system sharing features. You control these disclosures.
External links: If you open a website link, that site is governed by its own privacy policy. We are not responsible for third-party websites.

We do not sell or share your personal information for cross-context behavioral advertising. We do not engage in "selling" or "sharing" as defined by CCPA/CPRA.

4.1 Legal and safety reasons

We may disclose information if we reasonably believe it is necessary to comply with law, regulation, legal process, or government requests; to protect the rights, property, and safety of Ryft, our users, or the public; to investigate fraud or security issues; or to enforce our terms.

5) Data Retention

We retain personal information only as long as necessary for the purposes described in this Privacy Policy, or as required by law:

On-device data: Calculations, history, templates, sessions, and settings are stored on your device and remain there until you delete them using App controls or uninstall the App (subject to OS behavior).
Premium entitlement state: Cached locally on-device to reduce network checks. May persist until app uninstall or cache clearing.
Purchase/transaction metadata: Retained by platform providers (Apple/Google) according to their retention policies and legal obligations (typically for accounting, tax, and dispute resolution purposes).
Support communications: Email correspondence may be retained for up to 3 years for recordkeeping, legal compliance, and support quality improvement.

When data is no longer needed, we delete or anonymize it. You may request deletion of personal information we control (see Section 8 - Your Privacy Rights).

6) Security

We implement industry-standard technical and organizational security measures to protect information from unauthorized access, disclosure, alteration, or destruction, including:

Encryption in transit: We use TLS/HTTPS for all network communications where applicable.
Secure on-device storage: Premium entitlement state and sensitive data are stored using platform-provided secure storage APIs (iOS Keychain, Android EncryptedSharedPreferences) where supported.
Access controls: Access to backend systems (if any) is restricted to authorized personnel only.
Regular security assessments: We conduct periodic reviews and testing of security practices.

However, no method of electronic storage or transmission is 100% secure. While we strive to protect your information, we cannot guarantee absolute security. Please report security concerns to security contact (click to reveal).

7) Children's Privacy

The App is not directed to children under 13 (or the age defined by local law), and we do not knowingly collect personal information from children.

9) Regional Disclosures

9.1 United States (general)

If applicable law grants you privacy rights regarding personal information, you may contact us to request access, deletion, or correction for information we control (if any). Please note that most App content is stored locally on your device and may not be accessible to us.

9.2 California (CCPA/CPRA-style notice)

We do not knowingly sell or share personal information for cross-context behavioral advertising. We do not knowingly collect personal information from children under 16. If you contact us for support, we may process identifiers (such as email) and message content. If you make a purchase, billing providers may process transaction identifiers and purchase tokens under their own policies.

9.3 European Economic Area (EEA), UK, and Switzerland

If you are located in the EEA, UK, or Switzerland, see Section 2 (Legal Basis) and Section 8.2 (Your Rights) for GDPR-specific information.

International data transfers: When you make a purchase, your data may be transferred to and processed in countries outside the EEA/UK/Switzerland, including the United States, where Ryft LLC, Apple Inc., and Google LLC operate. These transfers are protected by:

Standard Contractual Clauses (SCCs): We rely on European Commission-approved SCCs for data transfers to third countries.
Adequacy decisions: Where applicable, we rely on adequacy decisions by the European Commission or UK government.
Platform provider safeguards: Apple and Google maintain their own GDPR compliance programs and data transfer mechanisms.

9.4 International users (general)

If you use the Services from outside the United States, please note that your information may be transferred to, stored, and processed in the United States and other countries where our service providers operate. These countries may have data protection laws that differ from your jurisdiction. By using the Services, you consent to such transfers where permitted by law.

9.5 Do Not Track

Some browsers offer a "Do Not Track" setting. The App is primarily offline and does not respond to browser DNT signals.

10) Data Breach Notification

In the unlikely event of a data breach that affects your personal information, we will take the following actions:

Notification to authorities: For EEA/UK/Swiss users, we will notify the relevant Data Protection Authority (DPA) within 72 hours of becoming aware of a breach, as required by GDPR Art. 33.
Notification to affected users: If the breach is likely to result in a high risk to your rights and freedoms, we will notify you without undue delay via the App, email (if we have it), or other appropriate means, as required by GDPR Art. 34 and applicable laws.
Mitigation measures: We will take immediate steps to contain and remediate the breach, and will describe the nature of the breach, likely consequences, and measures taken or proposed.

Note: Most App data is stored locally on your device and is not accessible to us. A data breach affecting our systems would likely involve limited information such as support communications or purchase verification metadata (if we operate a verification server).
