Who operates Foil Run
Foil Run is operated by Wren Dougherty in the United States. Wren Dougherty is the controller responsible for personal information covered by this Policy. Contact privacy@foil.run with a privacy question or request.
Information we collect
Depending on how you use Foil Run, we may collect:
- Account information: email address, username, display name, sign-in records, account settings, and records of your data choices.
- Session and location information: GPS coordinates, timestamps, speed, elevation, routes, session details, wind inputs and estimates, analysis results, Courses, spots, and public board entries.
- Gear and profile information: apparatus, foil, wing, board and other equipment details, notes, preferences, and the session and gear summaries the service creates. Possible future progression profiles and gear research are described below.
- Device and sensor information: device and app details, diagnostics, Watch calculations, motion and altimeter data when enabled, and heart-rate samples when you enable heart-rate upload or choose to import a file containing them. When you upload or record a track we keep the original file itself, which may contain additional fields your device wrote, such as temperature, cadence, or power.
- Voice and feedback information: voice recordings, transcripts, extracted session or gear details, feedback text, marked screenshots, reports, and contact details you choose to provide.
- Technical information: IP address, browser and device information, request and security logs, referrer, cookies, and similar information needed to run and protect the service.
- Product interaction information: while your current Help Improve setting permits it, an account-linked daily summary can record the server UTC day, a coarse web or app platform, and whether Logbook, a rendered result, or Compare was used. It does not store URLs, track or session identifiers, search queries, free text, geometry, audio, health or location data, visit counts, time spent, a device identifier, or an analytics cookie.
We receive information directly from you, from the Foil Run apps and the devices and services you connect, from Apple and TestFlight, from Google Play, and from service providers that help us operate requested features. We also create analyses, summaries, and inferences from the information above.
How we use information
We use personal information to provide and support Foil Run. Subject to the choices and limits below, our purposes also include improving the service and developing future features:
- provide accounts, recording, analysis, Logbook, recap, Course, and support features;
- calculate performance, wind, route, gear, and session insights;
- personalize the service and suggest relevant features or gear information;
- authenticate riders, prevent abuse, secure the service, and diagnose failures;
- communicate about the service and respond to questions and feedback;
- research, test, develop, and improve Foil Run under the choices described below;
- create de-identified and aggregate statistics, trends, maps, cohorts, and insights;
- comply with law and protect the rights, safety, and integrity of riders and Foil Run; and
- support a reorganization, financing, sale, or transfer of the service.
Your settings and choices
Foil Run uses separate controls for uses that are not necessary to provide a feature you request. Turning one choice off does not turn off the others or prevent ordinary recording and analysis.
- Help Improve: on by default for private session learning and aggregate analysis. It supports track and algorithm research, gear analysis, and improving voice transcription and extraction. You can turn it off at signup or in Account. It also controls the minimized daily product-interaction summary described above.
- External-AI voice processing: off until you enable it. It allows an external AI provider to process bounded voice-note material for transcription and session or gear extraction. A material change to the data or purpose requires new notice and, when required, a new choice.
- Heart-rate upload: off until you enable it on your device. Apple separately controls Health access.
- Motion capture: enabled by Apple’s Motion & Fitness permission. You can revoke it in Apple Settings.
- Report donation: one choice shares your report and available session information for private investigation and improvement, including external AI assistance. The form explains what is included before you send.
If you already turned a choice off, it stays off. Withdrawal blocks new processing that needs that choice. Turning off either current Help Improve choice also deletes retained daily product-interaction summaries for your account. It may not recall output already delivered or undo analysis that has been irreversibly de-identified. Processing already under way may continue where law permits.
Help Improve
Help Improve lets Foil Run learn from private sessions and aggregate results: test new algorithms, compare Watch and server analysis, study riding patterns and progression, understand gear performance and switching, and improve voice transcription and gear extraction.
Eligible data can include precise tracks, analysis results, session and gear details, app and device context, Watch calculations, eligible voice recordings and transcripts, voice-derived gear evidence, and motion data when separately enabled. Private session dig-in may use eligible recordings and transcripts to debug or improve transcription and extraction. Aggregate contribution may use the resulting de-identified topics and statistics. Eligible data can also include the minimized daily product-interaction summary described above, retained for up to 90 days. Heart rate is excluded from Help Improve, rider profiling, gear research, advertising, and partner output. A report you donate can contain health information needed to investigate that report, as explained below.
While the applicable Help Improve choice is active, eligible data may support the development, training, calibration, testing, and evaluation of Foil Run's own algorithms and models for the purposes described here. Possible future work includes private skill or progression groups, longitudinal gear adoption and switching, and broad riding-pattern maps. Describing this work does not mean every feature or research program is active today.
Each use remains subject to the restrictions that apply to its source data, including health and fitness data. A Help Improve choice does not authorize advertising or disclosure to equipment brands, and does not authorize an external AI provider to train its general-purpose models on your information.
AI and voice notes
Voice recordings and transcripts are private account data. Foil Run may process them locally or internally to organize your session and gear information and, while the applicable Help Improve choices are active, for the research described above. An external AI provider receives voice material only when the external-AI choice is active and only for the purpose described when you enable it. We do not add track geometry or recorded heart-rate data to that request.
External-AI voice permission covers your private session assistance, not a provider's general-purpose model training. Provider terms and account settings govern handling, including any limited retention for security, abuse prevention, or legal obligations. It is not a promise of zero retention. The request includes the contents of the voice recordings you choose to process, so avoid including sensitive details that are unnecessary for the feature.
Extracted titles, wind, and gear suggestions are presented as editable information. Foil Run may fill a clearly identified empty gear field and makes the result easy to review and change. It does not replace saved gear automatically.
When you donate a report, Foil Run may use external AI to investigate its text, optional contact details and available session evidence, including tracks and location, screenshots and analysis, gear, voice recordings and transcripts, motion and device diagnostics. This helps us reproduce problems, respond and improve Foil Run. Donation does not authorize a provider to train its general-purpose models on your information.
Aggregate and industry insights
Foil Run may create de-identified or aggregate information about rider progression, equipment adoption and switching, riding patterns, locations at an appropriate level of aggregation, performance, and feedback themes. We may use that information for research, product development, maps, reporting, and commercial decisions.
Industry Insights is a possible future program. We do not currently provide reports to equipment brands. If the program launches, eligible de-identified aggregate reports may be shared, licensed, or sold to equipment brands while your separate Industry Insights choice is active. Those reports may combine track-derived gear performance with themes derived from voice or written feedback. They do not include names, account or session identifiers, raw audio, transcripts, verbatim quotes, GPS points or precise routes, heart rate, Motion & Fitness data, or rider-level profiles. Release checks must suppress small or unusual groups and reduce re-identification risk.
Combining information into statistics does not necessarily make it nonpersonal. Information that can still identify a rider remains subject to this Policy and the applicable data choices. External industry reports must be de-identified; aggregation alone does not remove those protections.
Before a new program begins, we will provide the applicable notice and controls and meet the requirements for its data sources, purposes, and recipients. A new purpose or recipient does not automatically inherit an existing choice. Turning on Industry Insights does not authorize personalized advertising.
Foil Run does not currently sell personal information or share it for cross-context behavioral advertising. If that practice changes, we will update this Policy and provide any notice and opt-out or consent required by applicable law before the change takes effect.
Possible sponsored recommendations
We do not currently offer sponsored recommendations. We may develop paid placements, affiliate offers, or personalized gear recommendations in the future using eligible information, such as gear and preferences you provide. Before introducing such a use, we will explain the information used and provide any required choice or objection mechanism. Existing research choices do not enable it.
Sponsored placements will be clearly identified. Payment will not make unsuitable gear suitable or justify an unsupported performance claim. We do not use heart rate, HealthKit, Motion & Fitness data, or health inferences for advertising or marketing. Other information remains subject to the restrictions that apply to its source and intended use.
Location, motion, and heart rate
GPS tracks can reveal precise location and routine. Private session tracks are available only to you and authorized service operations, subject to the choices above. Weather lookup sends the coordinate and time needed for the request to the weather provider. Map providers receive the map area requested by your browser or app.
Motion and altimeter data are private and are collected only after the applicable Apple permission and Foil Run control allow it. Motion data may be used for Help Improve only while the relevant choices are active and the use is permitted for that data source. We do not use Motion & Fitness data for advertising, marketing, or industry reports. Foil Run does not use GPS or motion data to infer medical conditions.
Heart rate may enter Foil Run after Apple’s permission flow when heart-rate upload is enabled, or when you choose to import a file that already contains heart-rate samples. Raw samples remain private and are excluded from public hosted shares, Courses, leaderboards, Help Improve, industry insights, rider profiling, and advertising. Donated report evidence may include heart rate for private investigation of the reported problem, including the AI assistance explained at donation.
When you choose Share, a local recap may include average and maximum heart rate plus a coverage note when valid samples are available. It never contains raw samples, a time series, or heart-rate zones. The recap is created locally and is not hosted by Foil Run; you control where the resulting image is sent or saved.
Our separate Consumer Health Data Privacy Policy explains covered health information, its sources and disclosures, and how to exercise health-data rights.
Public actions
Ordinary session recaps are local files. Foil Run does not publish them for you. Older hosted share links may remain available until you remove the share or delete the associated session or account. Hosted shares never expose raw heart-rate samples.
When you publish a Course, its name, apparatus, area, gates, wind orientation, and other fields shown before publication become public. When you enter a Course board, the displayed rider, gear, result, and a line between the relevant gate crossings, with its timing and the turns or tacks measured between them, become public. Heart rate, voice, motion, and unrelated parts of the source session stay private.
Feedback and donated evidence
The general feedback form explains that sending your message permits private investigation and product improvement with an external AI provider. Selecting Send for AI review grants that permission for your message and optional email. No session data is attached. Providing an optional email lets us follow up about your report.
Donate all session info to help improve Foil Run is one choice. It covers your feedback and the available session evidence described in the form: your original track when available (otherwise a rebuilt track), location, analysis, marked screenshots, gear, voice notes and transcripts, motion and device diagnostics. This session-evidence donation is optional and separate from sending general feedback. Evidence stays private and supports investigation, regression tests, algorithm experiments, and gear and voice-processing improvements. Health information within donated evidence is used for the reported problem, not unrelated health research or advertising.
We retain donated evidence while reasonably needed to investigate the report, prevent regressions, improve the service, or establish what occurred. Retention may be indefinite while the evidence serves an ongoing regression purpose, subject to your request and applicable law. Feedback reports are not automatically matched to account deletion, so contact us if you want us to locate or delete a specific report.
When we disclose information
We may disclose personal information:
- to service providers that host, secure, operate, analyze, map, support, or communicate for Foil Run, under instructions and safeguards appropriate to their role;
- to an external AI provider when the applicable choice is active;
- to the public when you deliberately publish or share information;
- to comply with law, legal process, or a valid government request, or to protect rights, safety, security, and the integrity of the service; and
- in connection with a financing, reorganization, merger, sale, or transfer of the service, subject to applicable notice and privacy requirements.
Foil Run relies on service providers in these categories: application and database hosting, network and domain services, account email delivery, weather data, maps and related web infrastructure, platform and device services, and the external AI providers used for the voice and feedback choices described above. Providers may process information in the United States and other countries where they operate. You can ask privacy@foil.run which providers currently receive a given category of your information.
Legal bases
If European privacy law applies, we rely on:
- Contract and requested service to create your account and provide the features you choose;
- Legitimate interests to secure and support Foil Run, prevent abuse, diagnose problems, improve non-health features, and understand service performance, balanced against rider rights and expectations;
- Consent for external-AI voice processing, AI-assisted feedback review, optional health or sensor uses, industry insights, and other processing where consent is required;
- Legal obligation and vital interests when needed to comply with law or protect a person from serious harm.
Where a law requires a different basis, notice, consent, or opt-out for a particular use, Foil Run will apply that requirement before the use begins in that jurisdiction.
Rider alpha interest and platform requests
If you register rider alpha interest on the website, we keep the email address and/or Instagram handle you provide, phone and watch choices, optional device or setup details, selected research interests, optional description of what you want to work on, and a dated record of your permission. Foil Run uses these details to plan device support and alpha development and to contact you manually about those opportunities. The owner may record the last contact date or mark directly matching requests do not contact. The form does not send a message, create an account, or grant alpha access.
Requests are private to the owner and our hosting infrastructure. Registering requests planning and opportunity contact. It does not give Foil Run access to session data; that follows your Account settings and report donations. We keep requests while needed for the requested purpose. To withdraw permission, correct your details, or remove your request, email privacy@foil.run. Account deletion does not remove a separately submitted interest request. Backups follow their normal rotation.
Retention and deletion
We keep personal information only for as long as reasonably needed for the purposes described in this Policy, including providing the service, maintaining security and integrity, resolving disputes, meeting legal obligations, and preserving evidence you separately submitted for investigation or regression work.
Deleting a private session removes its active session data and attached source, voice, and motion material. Account deletion removes account-owned private sessions, account settings, sign-in records, and associated hosted shares and board entries. A public Course may remain without your attribution where needed to preserve other riders’ entries. Local recap files, copies held by others, separately submitted feedback reports, legal or security records, backups awaiting normal rotation, and irreversibly de-identified information may not be removed through the ordinary account flow.
Security and international processing
We use administrative, technical, and organizational safeguards designed to protect personal information. No storage or transmission system is completely secure, so we cannot guarantee absolute security.
Foil Run is operated from the United States. Information may be transferred to and processed in the United States and other countries that may have different data-protection laws.
Your privacy rights
Depending on where you live, you may have rights to access, correct, delete, or receive a copy of personal information; restrict or object to processing; withdraw consent; appeal a denied request; or opt out of certain sales, sharing, or profiling. You will not be discriminated against for exercising an applicable privacy right.
In the European Economic Area, United Kingdom, or Switzerland, you may also have a right to data portability and to complain to your local data-protection authority. In California, applicable rights may include knowing the categories, sources, purposes, and recipients of personal information and opting out of sale or cross-context behavioral advertising. Foil Run does not currently engage in those practices, so browser Do Not Track signals do not change its current behavior.
Washington law may treat heart rate and some linked activity or inferred information as consumer health data. Where that law applies, you may request access, deletion, or withdrawal of consent for covered collection or sharing and may appeal a denied request. Foil Run does not sell consumer health data.
Use the in-product controls where available or email privacy@foil.run. We may need to verify your identity and may retain a limited record of the request. Authorized agents may submit requests where the law permits. We will respond within the period required by applicable law.
Children
Foil Run is intended for adults and is not directed to children under 18. If you believe a child has provided personal information, contact us so we can investigate and take appropriate action.
Changes to this Policy
We may update this Policy as Foil Run, our practices, or the law changes. The date above identifies the current version. We will provide any notice, consent, opt-out, or other control required by applicable law before the affected processing begins. An update does not by itself turn on a separate choice or override a choice you turned off.
