1. How Alygn Works: On-Device Mode and Alygn Accounts

You can explore Alygn in two ways:

1. On-Device Mode (Browsing Without Submitting or Signing In): When you explore the Alygn web app without submitting the onboarding survey or signing in to an Alygn Account, your meal plans, preferences, and day logs are stored locally in your browser (localStorage and IndexedDB) on your device.
2. Coaching, Personalized Account & Improvement (Survey Submission & Signed-In Use):
   • United States & Standard Regions: When you submit the onboarding survey for a coach-reviewed plan or sign in to an Alygn Account, your agreement to our User Agreement and this Privacy Policy covers:
     • Coach Review of Your Plan: Sending your survey answers to an Alygn human coach so they can review and personalize your starting plan.
     • Personalized Account Storage: Saving your profile, preferences, meal plans, and logs to your Alygn Account so your guidance stays tailored to you across devices and visits.
     • Product Improvement: Using de-identified or aggregated patterns from what you share to improve Alygn's guidance, recipes, and food data for everyone. You can opt out of product improvement or cloud storage at any time with one click on your plan page (/plan/<key>) or in Data & Privacy (Settings).
   • European Economic Area (EEA), United Kingdom, and Switzerland: When you submit the onboarding survey from the EEA, UK, or Switzerland, sharing your answers with your Alygn coach and saving your personalized plan to your account are provided as the service you requested. Using what you share to improve Alygn for everyone is offered via a separate, unticked opt-in checkbox, and your coach-reviewed plan works in full whether or not you opt in.

2. Information We Collect

Depending on how you use the Service, we collect or process the following categories of information:

A. Survey, Wellness, and Dietary Information

• Goals and Preferences: Weight-management goals, eating styles, culinary preferences, cooking time/equipment, household size, and budget preferences.
• Allergies, Sensitivities, and Exclusions: Food allergies, intolerances, and ingredients you choose to avoid.
• Health and Medical Context: Self-reported health conditions (such as digestive, metabolic, or cardiovascular context), pregnancy or breastfeeding status, medications, supplement routines, sleep and stress patterns, and optional lab marker bands or body metrics (such as height, weight, age, and biological sex) used to calculate nutritional floors and targets.
• Free-Form Notes for Your Coach: Optional notes you write when submitting your survey for human coach review.

B. Meal Plans, Logs, and Scanner Inputs

• Planner and Check-In Data: Weekly meal plans, saved recipes, shopping lists, morning check-ins, habit streaks, and optional snack or restaurant meal logs.
• Photos and Scanned Text: Photos of restaurant menus, plates, grocery shelves, product nutrition labels, barcodes, or fridge contents that you choose to scan.
• Product & Recipe Contributions: Barcode numbers, label photos, or typed food queries you submit when asking Alygn to add or check a food item.

C. Account, Authentication, and Billing Information

• Account Identifiers: Your email address, authentication session tokens, and (if you sign in with Google) your basic Google account identifier and verified email address.
• Payment Information: When you purchase a coaching or subscription plan, payments are processed by Stripe. Alygn receives confirmation of your payment status and billing metadata from Stripe, but we do not store your full credit card number.

D. Technical, Diagnostic, and Usage Information

• Usage Beacons: When enabled under your privacy settings, Alygn records de-identified interaction events (such as which survey step or tab was reached, or whether a feature was used) to understand drop-off and improve the Service. Usage beacons do not include your typed health notes, meal logs, or email address.
• How You Reached Us: If one of our links brought you to Alygn, we note which link, or which kind of site. If you send your survey answers, your health coach also sees which one.
• Server and Security Logs: Standard HTTP request metadata (such as IP address, timestamps, and rate-limiting counters) used to protect the Service against abuse.

3. How We Use Your Information

We use the information we collect for the following purposes:

1. Providing Your Starting Plan and Coaching: Calculating your deterministic nutritional targets, generating meal plans, checking restaurant menus and grocery products against your goals and exclusions, and delivering your submitted survey to an Alygn human coach so they can prepare and send your personalized plan.
2. Syncing Your Alygn Account: When account storage is active, storing and syncing your chosen categories across your devices.
3. AI-Assisted Features: When you scan a restaurant menu, plate, fridge, or product label, or use AI-assisted meal-plan chat, the relevant image or prompt text and the dietary context permitted by your settings are sent through our server proxy to our AI inference providers to generate the response shown to you.
4. Improving Alygn (With Opt-Out Anytime): Where permitted by your regional consent and privacy settings, using de-identified or aggregated patterns (such as common food queries, recipe ratings, or aggregated survey completion patterns) to improve Alygn's catalog, nutrition rules, and guidance. This includes corrections you choose to send - picking from a short list that a scanned dish looks wrong - and how useful you said your plan was. These go to Alygn only while you are signed in and sharing to improve Alygn, carry no text you typed, appear in our internal exports under a pseudonymous key, and are removed when you delete your account. We never sell your personal information or use your data for third-party cross-context behavioral advertising.
5. Security, Transactional Emails, and Legal Compliance: Sending one-time sign-in codes and your coach-reviewed plan link, preventing fraud or abuse, enforcing rate limits, and complying with applicable legal obligations.

4. How Your Information Is Shared (Service Providers & Processors)

We do not sell or rent your personal information or consumer health data to third parties, and we do not share your information for third-party targeted advertising.

We share information only with your Alygn human coach (when you submit your survey or use coaching features) and with the following service providers acting as processors on our behalf under strict confidentiality and data-protection terms:

Capability Share Links: If you choose to create a shared shopping list link or view your plan via a capability link (/plan/<key>), anyone with whom you share that unique link can view the contents of that shared list or plan.

5. Data Storage, Security, and Retention

• Browser Storage: Data stored in your browser (localStorage and IndexedDB) remains on your device until you clear your browser data or use the Erase All Local Data control in the app.
• Cloud Storage & Security: When you submit a survey or sync an Alygn Account, data is transmitted over encrypted connections (HTTPS/TLS) and stored in Unison Cloud tables in the United States encrypted at rest, isolated by internal account or submission identifiers.
• Retention & Backup Aging:
  • Synced account records are retained while your account remains active and until you delete your cloud copy or your account.
  • When you delete your cloud copy or your account through the app, your records are removed immediately from active Unison Cloud tables. Residual copies in encrypted infrastructure backups are not restored to active use and age out automatically within normal backup retention cycles (within 6 months).
  • De-identified, non-reversible aggregate counts (such as how often a food name was searched) may be retained as statistical tallies that cannot be linked back to any individual.

6. Your Controls and Privacy Rights

Alygn provides direct, self-serve controls inside the app (Data & Privacy in Settings and on /plan/<key>) so you can exercise your choices immediately:

1. One-Click Opt-Out & Mode Switch: You can opt out of product improvement or switch your data preference at any time—including switching to Keep my data on this device only—from your plan page (/plan/<key>) or Data & Privacy in Settings.
2. Delete the Cloud Copy Alygn Holds: You can instruct Alygn to download any account records not yet in your browser, verify your local copy, and delete the synced records Alygn holds in the cloud while keeping your login active.
3. Delete Your Entire Account: You can permanently delete your Alygn Account, including all synced records, authentication sessions, and account identifiers, using the Delete my account button in Settings.
4. Erase All Local Data: You can clear all data stored in your browser at any time using the Erase All Local Data button.
5. Access, Correction, Portability, and Appeal Rights: Depending on where you live (including California, Washington, Nevada, Virginia, Colorado, Connecticut, Texas, Oregon, and the EEA/UK/Switzerland), you have the right to request access to, correction of, or portability of your personal information, to withdraw consent at any time, and to appeal a refusal to take action on a privacy request. You may exercise these rights directly in the app or by emailing us at [email protected]. We respond to verifiable requests within 30 days (or within 45 days where permitted by law, with notice). If we decline a request, you may appeal by replying to our response with "Privacy Appeal" in the subject line; if your appeal is denied, we will provide information on how to contact your state Attorney General or data protection authority.

7. Children's Privacy

The Service is intended for adults (18 years of age and older) and is not directed to children under 13 (or under 16 where applicable). We do not knowingly collect personal information from children.

8. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. When we make material changes, we will update the "Last Updated" date and version number at the top of this page and, where required by law or where we ask to expand how your synced account data is used, notify you in the app.
