Sisu Ascent (“Sisu,” “we,” “us”) is operated by Sisu Ascent LLC. This policy explains what we collect, how we use it, and the choices you have. We built Sisu to respect your data: we do not run ads, we do not use third-party advertising or analytics trackers, and we never sell your information.
Information we collect
Account information. When you create an account, we collect your email address to sign you in and sync your data. Authentication is handled through our hosting provider (Supabase).
Health, fitness, and nutrition data you provide. Sisu stores the information you enter: body weight, body-fat percentage and measurements, workouts and personal records, meals and nutrition, supplements, water intake, check-ins, goals, and progress notes. This data is stored on your device and, when you are signed in, backed up to our cloud so you can restore it and use multiple devices.
Photos. With your permission, Sisu uses your camera to scan barcodes (these images are processed on-device and not stored) and to take progress photos and meal photos. Progress and check-in photos you save are stored with your account. When you use the AI “snap a meal” feature, the meal photo is sent to our AI provider to estimate its nutrition.
Food-search queries. When you search foods, your search terms are sent to USDA FoodData Central and Open Food Facts to return nutrition information.
AI feature inputs. When you use AI features (meal suggestions, recipe and macro estimation, supplement guidance, snap-a-meal), the text or photo you submit is sent through our secure server to our AI provider (Anthropic) to generate a result. Our API keys are held server-side and are never included in the app.
Notifications. If you enable reminders, we use a device push token (via Apple Push Notification service / Expo) to deliver the notifications you turn on.
Community sharing (optional)
Sisu lets you optionally publish recipes to share with other users. If you choose to publish a recipe, the recipe content and the display name you enter at the time of publishing become visible to other users (publicly in the community library, or to anyone with the share code if published unlisted). Only what you deliberately publish is shared — your account email, logs, weight, photos, and other personal data are never shared. Do not include personal or sensitive information in content you publish. You can unpublish a recipe at any time, though copies other users already saved to their own libraries may remain with them. You can report objectionable shared content from within the app.
What we do NOT collect
- No advertising identifiers, ad networks, or behavioral ad tracking.
- No third-party analytics, marketing, or crash-tracking SDKs.
- We do not sell or rent your personal information to anyone.
How we use your information
We use your data only to: provide and operate the app’s features; back up and sync your data across your devices; generate the AI suggestions you request; deliver reminders you enable; and maintain the security of your account.
Service providers
We share the minimum data needed with providers that process it on our behalf:
- Supabase — secure hosting, authentication, and database/backup.
- Anthropic — processing AI feature requests you initiate.
- USDA FoodData Central and Open Food Facts — returning food/nutrition data for your searches.
- Apple / Expo push services — delivering notifications you enable.
Data storage and security
Data is transmitted over encrypted connections (HTTPS/TLS). Cloud data is protected with per-user access controls (row-level security) so your data is isolated to your account. No system is perfectly secure, but we take reasonable measures to protect your information.
Your choices and rights
- Access: your data is viewable in the app at any time.
- Sign out: clears the locally stored data on that device.
- Reset All App Data: permanently deletes your data in the cloud and on the device.
- Delete account: email support@sisuascent.com and we will delete your account and associated data.
- Permissions: you control camera, photo, and notification access in your iOS Settings at any time.
Future features
We plan to add optional integrations that, only with your explicit permission, will access additional data:
- Apple Health (HealthKit) — to read/write health and fitness data such as steps, workouts, weight, and heart rate.
- Location (GPS) — to track outdoor runs and rides.
These will be opt-in, and we will update this policy before they launch.
Children’s privacy
Sisu is intended for users 18 and older and is not directed to children. We do not knowingly collect data from anyone under 18. If you believe someone under 18 has provided us data, contact us at support@sisuascent.com and we will remove it.
Changes to this policy
We may update this policy as the app evolves. We will post the revised version with a new “Last updated” date.
