Tune Terms of Service

The complete product agreement: product-specific terms, incorporated schedule, Apple purchase rules, limited mode, and signed document evidence.

Document ID service-termsVersion 5.0.0Effective 2026-08-06com.ryantinklepaugh.tune

Agreement for one product. These Terms apply only to Tune (com.ryantinklepaugh.tune). Acceptance is recorded against this document’s exact version and SHA-256 hash, the separate product Privacy Policy, and the separate Product Schedule.

Product-specific schedule incorporated into these Terms

Product-specific document. This schedule applies only to Tune (com.ryantinklepaugh.tune). It supplements the separate Tune Terms of Service and Privacy Policy, each with its own immutable version and SHA-256 hash.

Product purpose

Tune is a guided room-acoustics and subwoofer-alignment aid for measuring a listening position, explaining low-frequency response, comparing changes, and verifying whether a placement, polarity, delay, or conservative equalization experiment improved the measured result.

Acoustic guidance, not certified instrumentation

Tune is an acoustic setup aid. It is not a certified sound-level meter, hearing test, medical device, building-code instrument, laboratory analyzer, or substitute for calibrated professional instrumentation. It does not claim absolute sound-pressure accuracy from an iPhone microphone or compliance with IEC, ISO, REW, or another measurement standard.

A result describes the selected route, equipment, placement, listening position, sweep, noise conditions, and calibration state at the time of measurement. Background noise, reflections, clipping, automatic gain behavior, microphone variation, device cases, route processing, movement, or an incorrect calibration file can produce incomplete or misleading results.

Audio-route and timing limits

Built-in, Bluetooth, AirPlay, and other routes that are not timing-qualified remain magnitude-only. Tune does not provide delay, distance, or polarity advice from those routes. Timing and polarity analysis requires a full-duplex wired or USB route that passes the app's route, marker, repeatability, and stability checks across repeated sweeps.

Passing a software check does not certify the connected interface, microphone, speaker, subwoofer, or room. Confirm the displayed route and repeat the verification measurement after making a change.

Audible sweeps and safe equipment use

Tune produces audible test sweeps. Set a conservative playback level, protect hearing, avoid disturbance, and use speakers, subwoofers, amplifiers, interfaces, microphones, and cables within their instructions and limits. Stop if a sweep is uncomfortable, distorted, unstable, or appears likely to damage equipment.

Do not use Tune where an audible signal could create a hazard or interfere with communication, alarms, care, work, or another person. Tune does not monitor hearing safety or equipment temperature and cannot prevent damage caused by level, wiring, configuration, or equipment failure.

Recommendations are experiments to verify

Placement, polarity, delay, target-curve, and cut-only parametric-equalization suggestions are conservative starting points, not guarantees. The user must decide whether a proposed change is appropriate for the equipment and room, apply it using the equipment manufacturer's controls, listen at a safe level, and remeasure.

Free access and Tune Pro

The current Free tier supports one room, up to three saved measurements, the balanced target, and the guided room-response scan shown in the app. Tune Pro can add unlimited rooms and history, timing-qualified subwoofer alignment, alternate target curves, before-and-after comparison, conservative cut-only PEQ suggestions, calibration-file import, and CSV or JSON export.

Tune Pro may be offered as an annual auto-renewable subscription with the Apple-disclosed introductory offer for eligible users or as a one-time lifetime purchase. The Apple purchase sheet controls the current price, trial eligibility, product type, renewal terms, and included features.

Limited mode

A user who declines or withdraws remains able to review available local records; export or delete available product data; read legal and support information; and manage or restore an Apple purchase. New or edited rooms, scans, comparisons, calibration imports, private-iCloud product writes, recommendations, new purchases, and Pro measurement or alignment features can remain unavailable until the current product documents are affirmatively accepted.

Current product data boundary

The following categories and operational boundaries are specific to Tune and form part of this schedule.

Microphone input and on-device analysis

Tune requests microphone access only to run a scan the user starts. It plays an audible sweep, reads microphone samples, checks the route and signal, and performs the acoustic analysis on the device. Raw microphone buffers remain in memory only during that analysis. Tune does not save them as an audio recording, upload them to Uncommon Weather, CloudKit, RevenueCat, or the legal-choice service, or use them for advertising.

The saved result contains derived frequency-response values, route capability, quality and repeatability checks, findings, comparisons, measurement lineage, and, only on a timing-qualified route, derived timing or polarity results. These derived records describe a room and audio system rather than preserving intelligible microphone audio.

Local records and private iCloud synchronization

Tune stores rooms, derived measurements, findings, imported calibration data, settings, synchronization state, generation epochs, and deletion tombstones in files protected on the device. The app remains useful offline and does not require a Tune account or a developer-operated measurement backend.

When the user's device and iCloud settings permit, Tune synchronizes derived product records through a custom zone in the user's private CloudKit database. Apple processes those records under the user's iCloud account and Apple's terms. Tune does not send a second copy to a developer-operated measurement server, and support cannot restore a user's private CloudKit records.

Calibration imports and user-directed exports

A calibration-file import reads the frequencies, correction values, filename, and validation information needed to apply the selected microphone correction. Tune does not upload the calibration file to Uncommon Weather. The user is responsible for selecting a file that is appropriate for the microphone and measurement setup.

Tune creates CSV or JSON output only after the user requests an export. The iOS share or file interface lets the user choose the destination. Copies saved, sent, or uploaded by the user remain with that destination or recipient until deleted there and are governed by its terms and retention controls.

Apple processes App Store purchases and payment credentials. RevenueCat receives an anonymous app-user identifier and limited app, device, offering, product, transaction, purchase, and entitlement metadata needed to present Tune Pro, restore purchases, provide aggregate subscription analytics, and determine access. Tune does not set an email address or custom account identifier in RevenueCat and does not send raw microphone audio, room names, measurements, calibration files, or exports to RevenueCat.

The separate Uncommon Weather legal-choice service receives only signed, privacy-minimal evidence of an acceptance, decline, or withdrawal, including product and document identifiers, versions and hashes, the choice, adult age band and acceptor role, pseudonymous installation and request identifiers, app version and build, timestamps, locale, source and sequence, cryptographic proof, and receipt linkage. It does not receive Tune rooms, measurements, raw audio, calibration data, exports, iCloud identifiers, or purchase history.

Retention and deletion

Tune keeps local derived records until the user deletes them or removes the app, subject to Apple's storage behavior. Its delete-all flow requests removal of local product records and records in the app's private CloudKit zone. If the device is offline or Apple temporarily rejects part of the request, Tune retains privacy-preserving deletion state and retries so older synchronized data is not treated as current merely because another device reconnects.

A completed product deletion does not erase CSV or JSON copies the user already saved or shared, Apple or RevenueCat purchase records, provider security records, or privacy-minimal legal-choice evidence retained for integrity, security, legal claims, or compliance. The user must delete exported copies at each destination and manage or cancel an Apple subscription separately.

A decline or withdrawal takes effect locally at once and remains limited without a recurring prompt. A user can review the current documents and affirmatively accept from Legal & Privacy settings. A current affirmative acceptance takes effect after it is durably saved on the device and unlocks main-app access while signed-receipt delivery retries in the background. A non-terminal network, Apple, or service outage does not lock the main app or create another prompt. Widgets, Live Activities, and other extension surfaces that require a verifiable cross-process receipt may wait until the server-signed receipt is received and verified. If the server explicitly rejects the exact saved acceptance as terminal, the client quarantines that failed record and returns to the appropriate decision or limited-state screen. A current choice is not repeatedly requested.

General contractual provisions

1. Operator and documents

These Tune Terms of Service (“Terms”) are between you and UNCOMMON WEATHER LLC, with a notice address at 1212 N Walker Ave Apt 207, Oklahoma City, OK 73103, United States (“Uncommon Weather,” “we,” “us,” or “our”). Contact team@uncommonweather.com for support, legal notices, and privacy requests.

These Terms incorporate the Tune Privacy Policy, the separately hashed Tune Product Schedule, and mandatory Apple platform rules. Apple’s Standard Licensed Application End User License Agreement also applies unless Apple or the App Store listing identifies a valid custom EULA. If documents conflict, mandatory law controls, then Apple terms where they must control, then the Product Schedule for product-specific matters, then these Terms.

2. Adult eligibility and agreement

You must be at least 18 and accept these Terms for yourself. Tune is not offered for use by a minor, and a parent or guardian cannot accept on a minor's behalf. No birth date is collected; the acceptance flow records only a broad adult age band and acceptor role.

Clicking “Agree & Continue” after checking the agreement control creates an affirmative acceptance tied to the displayed document versions and hashes. Declining leaves legal, support, export or deletion, and Apple purchase-management or restoration controls available as described in the Product Schedule, but disables ordinary product operation.

3. Limited license and acceptable use

Subject to these Terms and any required payment, Uncommon Weather grants you a limited, personal, revocable, non-exclusive, non-transferable license to install and use Tune through an Apple-authorized distribution channel. You may not resell, sublicense, bypass licensing, reverse engineer except where law permits, introduce malicious code, interfere with services, violate Apple platform rules, infringe another person’s rights, or use the app to break the law.

4. Ownership, content, and feedback

Uncommon Weather and its licensors retain rights in Tune, its brand, design, code, documentation, and services. You retain your rights in content and records you create or capture and are responsible for having permission to use or share them. Feedback may be used without restriction or compensation.

5. Apple purchases, renewals, and refunds

Tune Pro may be offered as an annual auto-renewable subscription and as a one-time lifetime purchase through Apple. The current price, trial eligibility, duration, renewal terms, included features, and product type shown by Apple before confirmation control. The annual plan renews until cancelled through Apple; the lifetime product is a non-consumable purchase for the supported app features and is not a promise that every service or platform will exist forever. Deleting Tune data does not cancel an annual subscription. Apple handles billing, cancellation, refunds, and purchase management. RevenueCat supplies anonymous purchase and entitlement state to Tune but does not process the payment.

An auto-renewable subscription continues until cancelled through the Apple ID subscription controls. Cancellation normally stops future renewal after the current paid period and does not automatically refund an earlier charge. Request an eligible refund through Apple. Mandatory consumer rights continue to apply, and a full refund may revoke the associated paid entitlement.

6. Product data, exports, and backups

Tune stores rooms, derived measurements, findings, comparisons, calibration-file data, settings, synchronization state, and deletion state in files protected on the device. When private iCloud synchronization is available, Tune can synchronize those derived records through the user's private CloudKit database and custom zone. Tune has no product account and no developer-operated measurement server. Raw microphone audio is held in memory only while a user-directed scan is analyzed and is not retained as a recording or uploaded. Private CloudKit synchronization is not a guaranteed backup, and offline edits, device loss, app removal, iCloud settings, storage failure, corruption, conflict resolution, or Apple service changes can cause loss or reduced functionality. CSV and JSON files created at the user's request remain wherever the user chooses to save or share them.

7. Apple and other service providers

Tune may rely on Apple, iOS, AVFoundation and other audio frameworks, the App Store, StoreKit, private CloudKit, push notifications used for private synchronization, RevenueCat for anonymous purchase and entitlement state, and Supabase only for the separate privacy-minimal legal-choice service. Those providers apply their own terms and can change, fail, restrict, or discontinue service. Uncommon Weather does not control third-party platforms, audio routes, microphones, speakers, rooms, accounts, or acoustic conditions.

8. Updates, availability, and termination

We may update Tune for security, law, policy, compatibility, reliability, or product reasons. We do not promise uninterrupted, error-free, or permanent availability. We may suspend network services for abuse, security risk, legal requirements, or material breach. You may stop using the app at any time.

Declining materially updated terms places the app in limited mode rather than deleting prior acceptance or local data. Ownership, payment obligations, disclaimers, liability limits, indemnification, and disputes survive termination where applicable.

9. Disclaimers

TO THE MAXIMUM EXTENT PERMITTED BY LAW, TUNE AND ITS SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE.” UNCOMMON WEATHER DISCLAIMS IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AND UNINTERRUPTED OR ERROR-FREE OPERATION. Product-specific limitations appear in the Product Schedule.

10. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, UNCOMMON WEATHER AND ITS MEMBERS, MANAGERS, CONTRACTORS, TRANSFERORS, AND LICENSORS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, CONSEQUENTIAL, OR PUNITIVE DAMAGES; LOST PROFITS, REVENUE, DATA, GOODWILL, OR OPPORTUNITY; OR SUBSTITUTE SERVICES, ARISING FROM OR RELATED TO TUNE OR THESE TERMS, EVEN IF ADVISED OF THE POSSIBILITY.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, TOTAL LIABILITY FOR ALL CLAIMS RELATED TO TUNE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID FOR THE APP DURING THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM OR (B) US $100. These limits do not apply where prohibited, including non-waivable liability for fraud, willful misconduct, or certain personal injury and consumer rights.

11. Indemnification

To the extent permitted by law, you will defend and indemnify Uncommon Weather from third-party claims, damages, and reasonable costs arising from unlawful use, content you had no right to use or share, infringement, intentional misuse, or material breach. This does not apply to claims caused by Uncommon Weather’s own conduct and remains subject to mandatory consumer-law limits.

12. Governing law and disputes

Before filing a claim, send a written description and requested resolution to the notice address or email and allow 30 days for informal resolution unless urgent relief or mandatory law makes that impractical. Oklahoma law governs without regard to conflicts rules. Subject to mandatory consumer venue rights, state and federal courts serving Oklahoma County, Oklahoma have exclusive jurisdiction.

These Terms do not require arbitration and do not contain a class-action waiver. Nothing limits eligible small-claims proceedings or non-waivable rights.

13. Changes and document evidence

Material changes receive a new version and require a new affirmative acceptance before ordinary use. Immutable archived copies and SHA-256 hashes identify what was presented. Continued use alone does not silently create acceptance of a materially changed document.

14. Assignment, severability, and notices

You may not assign this agreement without consent. We may assign it with the app, business, merger, reorganization, or asset sale subject to applicable law and required notice or consent. If a provision is unenforceable it will be limited to the minimum necessary and the remainder continues. Failure to enforce is not a waiver. Neither party is liable for delay caused by events beyond reasonable control.
