Privacy Policy
This policy explains what Glidna (operated by Smooth Training LLC — "we," "us") collects, how it's used, and the choices you have. The short version: your fitness data is yours, we use it only to run Glidna, and we never sell it.
1. What we collect
- Account info: name, email, and your role (client or trainer).
- Fitness & health data you enter: weight, goals, body measurements, food and calorie logs, workouts, water intake, check-ins, and notes.
- The details the calorie maths needs: your date of birth or age, sex, height and activity level. When you sign up you also confirm you're 18 or older, and we keep that yes with the date and the version of our Terms you agreed to.
- Health information: anything about your health that you or your coach write into Glidna, such as an injury, a medical condition, a medication or a pregnancy. Your coach's own coaching notes about you can include this kind of information. Those notes are for your coach and aren't shown on your screens.
- Addresses and location: the addresses you enter for training sessions (and, for a coach, where they start their day). While you type an address, what you've typed so far is sent to Google Maps to suggest matches. If you tap On my way and allow it, your device's location is read once to work out an arrival time. It's sent to Google Maps for that and is never stored. If you say no, the other person is still told you're on the way. We don't track your location in the background.
- Signed documents: a waiver or agreement your coach sends you to sign, the signed copy, and when you signed it.
- Glide's memory and commitments: short facts Glide keeps from one chat to the next so it doesn't have to ask again (for example "doesn't like fish" or a usual restaurant order), and any commitment you ask it to hold you to ("walk every day for a week"), with the reminders you chose and how each day went. You can ask Glide what it remembers, and tell it to forget something or end a commitment, at any time.
- Your conversations with Glide: what you and Glide say in the app's chat, by text or WhatsApp, and on calls with Glide is kept for one year, so Glide can look back when you ask ("what was that protein bar you told me about?"). Your coach, and the head coach above them, can search your conversations with Glide too, to prepare for a session or follow up on something you said. Link codes and other codes are removed before anything is shown, and your coach's private notes are never shown back to you. Deleting your account deletes all of it.
- Progress photos: before and now photos of your body that you (or, after your yes, your coach) choose to save, with the date, the angle and any note. They're kept until you delete them, or your account is deleted. Only you see them unless you turn on "Let my coach see my progress photos"; then your coach and the head trainer above them can see them too, until you turn it off. They aren't available to anyone under 18. Glide looks at two of them only when you, or your coach after your yes, ask it to compare them (see §2), and never sends a progress photo by text, a call, email or a connected AI app.
- Content you send: messages with your trainer, chats with the AI assistant, and any meal photos or voice recordings you choose to share with it.
- Your phone number, if you text or call our number or turn on texts (see §7), and the record of when and how you said yes.
- Connected-service data you authorize — for example, fitness-tracker stats (daily burn, steps) synced from Trainerize, the coaching app your trainer may use (see §3).
- WHOOP or Oura, if you connect one: once you sign in to WHOOP or Oura and approve it, we read your daily summaries from it about once an hour: time asleep and your sleep score, your recovery (WHOOP) or readiness (Oura) score, heart-rate variability, resting heart rate, strain (WHOOP), calories burned and steps. We read only those summaries. We don't read your WHOOP or Oura profile, your workouts, your location or your heart rate minute by minute, and we never send your Glidna data to WHOOP or Oura.
- Apple Health or Health Connect, if you connect one in the Glidna app: after you agree on your phone, the app reads your steps, active and resting calories, workouts (type, length, calories and distance), resting heart rate, heart-rate variability, time asleep and VO2 max, for the last 7 days, each time you open the app. We use them only to show your own days (what you burned, your workouts, your sleep) to you and to your own coach, and so the AI assistant can answer you about them if you ask it. We never write anything to Apple Health or Health Connect, never sell this data, never use it for advertising or marketing, and never share it with anyone else, except the service providers that run Glidna for us (§3): when you ask the AI assistant about it, the part it needs to answer goes to our AI provider, Anthropic, as described in §2. We don't store it in iCloud. You can turn it off in the app (≡ → Settings) and take back the permission in your phone's settings at any time; deleting your account deletes what we stored (see §5).
- Payment info: handled entirely by Stripe — we never see or store your card number, only your subscription status.
- Basic technical data: device/browser type and app activity needed to keep Glidna working and secure.
- App updates (the iPhone and Android app only): to check for and install a newer version of the app, it sends our update provider, Capgo, a random ID the app makes for your device (not your name, email, account or your phone's advertising ID), the app's and your phone system's version numbers, and whether an update downloaded, installed or failed. Your network address reaches Capgo as part of any connection. Capgo gets none of your Glidna data, and this is used only to deliver updates and catch a broken one, never for ads or to track you.
- Connector activity: if you connect an outside AI assistant (see §3), we record a per-day count of its requests to enforce fair-use limits, plus the standard server logs above. We do not store the conversations you have with your assistant.
2. How we use it
- To run Glidna: your dashboards, plans, projections, streaks, and calendars.
- AI features: when you use the AI assistant, your message (and the relevant fitness data or photo needed to answer) is sent to our AI provider (Anthropic) to generate the response. Voice notes are transcribed by a speech-to-text provider. When you tap Listen under an answer, that answer's words are sent to a text-to-speech provider (ElevenLabs) to make the audio. So it's made once and replays free, we keep a copy of the answer for up to 60 days and its audio for up to 30, and deleting the chat deletes both. A message from your coach may end in a "Hear this read aloud" link; when you open it, that message's words are sent to ElevenLabs the same way, and we keep the words and the audio for 30 days. The link plays only that message. We use API services whose terms prohibit training their models on your data.
- WHOOP and Oura readings show on your day in Glidna, where your trainer (if you link one) can see them, and the AI assistant can read them when it answers you (sent to Anthropic the same way as the rest of your data above). Your calorie target follows the device's calories burned only if you turn on "use my watch burn" in your plan, and never goes below 1,200 calories a day. We don't use these readings for anything else.
- To send notifications you've enabled (reminders, messages, to-dos) — every type has a toggle in the app's Notification Center.
- To bill subscriptions (Stripe) and send invitation emails you request (Resend). If you pay by the year, we email you before each yearly renewal with the date, the amount and how to cancel.
- Drive times and mileage: session addresses are turned into a point on the map (by Google Maps, or by OpenStreetMap's Nominatim service when Google can't place one) so Glidna can work out a coach's drive time between sessions and, for a coach who turns it on, keep a mileage log for their own business records. Only the address is sent, never your name.
- Looking things up: when Glide needs something from the web (a restaurant's menu, say), it writes a search and Anthropic's web search tool runs it. The search words go to Anthropic, which may use a search partner to run it; your account details don't. Food you search for or scan is looked up in the USDA's FoodData Central database (through our servers) and in Open Food Facts (straight from your device, so Open Food Facts receives your device's IP address). Only the food name or barcode is sent.
- We don't use your data for advertising, and we don't build a profile of you for anyone else.
3. Who can see your data
Your trainer, if you link one. Linking with a trainer authorizes that trainer (and their head trainer, if they work under one) to view and edit your fitness data — plans, logs, weigh-ins — and to message you. This is the point of the platform, but it's always your choice: unlinking (Home → Leave trainer) ends their access to future data. No other Glidna user can ever see your data.
Glidna’s administrator, to help you. The person who runs Glidna for Smooth Training LLC can open a read-only copy of your home screen, the same one you see, along with how far you are in setting up: which set-up steps you’ve finished and when you last opened the app. It’s used only to help you get started or sort out a problem. Nothing can be changed, sent or charged from it.
AI assistants you connect yourself. You can connect Glidna to an outside AI assistant (such as Claude) so it can work with your Glidna data on your behalf. This only happens if you start the connection and approve it on our permission screen, and you choose what it may do — reading your data, and (where offered) logging entries for you.
When you connect an assistant, the information it requests is sent to that provider, and from that point it is handled under your agreement with them and their privacy policy, not ours — including how long they keep it and whether they use it to improve their services. We cannot control or delete data once it is in your assistant's hands. Please review your AI provider's privacy terms before connecting.
A connected assistant can never see more than you can. It uses the same permission rules as the app: your own data, and — if you are a trainer — the clients already linked to your account. It cannot reach anyone else's information. You can disconnect at any time in your AI assistant's settings; disconnecting stops all future access immediately, but it does not retrieve data your assistant already received.
WHOOP and Oura. Data goes one way, from your device's account into Glidna. The access WHOOP or Oura gives us is stored where no Glidna user, trainer or screen can read it, and it's used only to fetch your readings. Your readings are covered by this policy once they're in Glidna; what WHOOP or Oura themselves do with your data is covered by their own privacy policies.
Trainerize. If your coach works with you in Trainerize (the coaching app Smooth Training uses), Glidna and Trainerize exchange data in both directions. From Trainerize, Glidna reads your profile, your workout calendar and programs, the workouts you finish, your watch stats (such as calories burned and steps), your nutrition logs and goals, body stats, and your messages with your coach. Into Trainerize, Glidna writes your workout programs and messages to you from your coach or from Glide, Glidna's AI, including Glide's answers when you write to it there. Of what you enter in Trainerize, only watch stats and finished workouts change your Glidna data. What Trainerize itself does with your data is covered by its own privacy policy.
Service providers that make Glidna work process data on our behalf: Google Firebase (database, sign-in), Anthropic (AI responses generated inside Glidna), Groq/OpenAI (voice transcription), ElevenLabs (reading answers and coach messages aloud, when you tap Listen or open a read-aloud link), Stripe (payments), Resend (email), Twilio (text messages and calls), SignNow (documents your coach sends you to sign, such as a waiver), Google Calendar (if your coach connects theirs, your sessions with them appear on it), Google Maps Platform (address suggestions, map points, drive times and routes), OpenStreetMap Nominatim (a backup for turning an address into a map point), USDA FoodData Central and Open Food Facts (food lookups), Capgo (updates to the iPhone and Android app, see §1), and Vercel (hosting). Each receives only what its job requires.
We do not sell your personal data, and we don't share it with advertisers. We'd disclose data only if legally compelled.
4. Security
Data is encrypted in transit; access is enforced by server-side security rules that are tested before every change (your data is readable only by you, your linked trainer chain, and our administrator). Sign-in supports passkeys (Face ID / Touch ID), which never leave your device.
Where it's stored. Your Glidna data is stored on our servers, in Google Firebase's data centers in the United States. The app also keeps a copy on your own device, so it opens quickly and works without a connection, and it syncs when you're back online.
If something goes wrong. If there's ever a breach of your health or fitness information, we'll tell you without unreasonable delay and no later than 60 days after we find it, and we'll tell the Federal Trade Commission (and, where the law requires, the media), as the FTC's Health Breach Notification Rule requires.
5. Your choices & rights
- Export: you can export your data from the app anytime.
- Delete: in the app, ≡ → Delete my account. You confirm it's you, and your account and everything in it are deleted straight away: plans, logs, meals, photos, notes, chats and connected-device links. If your plan is paid up, you keep using Glidna until the end of what you paid for (you won't be charged again, and there's no refund for the rest of that period), and your account is deleted that day; you can undo it until then. Two things stay, because they're also someone else's records: session bookings and payment records shared with your coach, kept without your name, and the record of the card agreement you gave for paid sessions, kept privately in case of a payment dispute. Stripe keeps its own payment records under its own policy. A coach who still has clients releases or hands them over first. You can also email us at the address in §9 and we'll do it for you.
- Delete some of it: you don't have to close your account to remove something. Delete a logged meal or workout, a photo, a note of your own or a whole chat from where it appears in the app, and it's deleted from our servers too. To have something else removed, email us at the address in §9.
- Notifications: every notification type is a toggle in the app.
- Unlink: leave your trainer at any time to end their access.
- Disconnecting WHOOP or Oura: in the app, ≡ → WHOOP or Oura → Disconnect. We stop reading straight away, ask WHOOP or Oura to cancel our access, and delete it from our records. Readings already in your log stay there as part of your data: you can export them, and deleting your account deletes them. Removing Glidna in the WHOOP or Oura app also stops it.
- Disconnecting an AI assistant: remove Glidna from your AI assistant's connector settings. You can also ask us to revoke a connection at the address in §9 and we'll invalidate the credentials so the assistant loses access.
6. Retention, children, changes
We keep your data while your account exists and delete it when you delete your account (§5). Your conversations with Glide are kept for one year, then deleted automatically. Glidna is for adults 18+: you confirm you're 18 or older when you sign up, and setting up your own plan stops if the age or birthday you enter is under 18. If we learn that someone under 18 has made an account, we'll delete it. If we materially change this policy, we'll announce it in the app before it takes effect.
7. Text messages
Smooth Training LLC sends Glidna's text messages. You can text Glidna's number, (754) 289-3279, to log meals and workouts, ask questions and reach your coach. You only get texts from us after you say yes: by texting the number first (for example, texting GLIDE) or by turning on texts in the app.
- What we text: answers to your texts from Glide, Glidna's AI assistant, or from your coach; reminders and check-ins you chose; and account messages such as sign-in codes. We don't send marketing texts.
- Who sees your texts: the same people who can see your Glidna data (§3). Glide reads a text to answer it, and can search your past texts when you or your coach ask it to (kept one year). Someone you add to your texts (a partner or parent) agrees by text, before Glide answers them, that their messages are kept for a year and can be seen and searched by you and your coach.
- Your stats by text, call or email: you can agree, once, to have your stats (weight, body measurements and others) sent to you by text, call or email, and to have your coach's requests for them answered the same way, only to a phone or address verified on your coach's own account. Turn it off any time by telling Glide "stop sharing" or with the switch in Settings. Never for anyone under 18.
- Your phone number and your yes stay with us. We do not sell or share your SMS opt-in data or personal information with third parties for marketing purposes. We don't share your mobile information with third parties or affiliates for marketing or promotional purposes, and we don't share your text-message opt-in data or consent with any third party. Twilio, which delivers the texts, gets only what it needs to deliver them.
- Stopping: reply STOP at any time and the texts stop. Reply HELP for help. Message frequency varies, and message and data rates may apply.
8. Consumer health data (Washington, Nevada and similar laws)
Some of what Glidna holds is "consumer health data" under laws such as Washington's My Health My Data Act and Nevada's SB 370: information about your body and health. This section says how we treat it, wherever you live.
- What it is: weight, body measurements and body composition; food, calorie and water logs and meal photos; progress photos of your body; workouts, calories burned, steps, heart rate, heart-rate variability, sleep and recovery from a watch or ring you connect; health conditions, injuries, medications or a pregnancy written in Glidna by you or your coach; and the parts of your chats, voice notes and Glide's memory that are about your health.
- Where it comes from: you; your coach, if you link one; the devices and apps you connect (WHOOP, Oura, Trainerize); and what Glidna works out from them, such as your calorie target and estimated burn.
- Why we use it: only to give you the service you asked for: your plan, logs, projections and reminders, your coach's view of your progress, and Glide's answers. We don't use it for advertising, and we don't use location to draw a virtual fence around a clinic or any other place that provides health care.
- Who we share it with: your coach and their head coach, if you link one (§3); the service providers in §3, each only for its job; an AI assistant you connect yourself; and anyone a law or court order requires us to tell. We never sell it. We collect and share it only as needed to give you the service you asked for, or with your consent.
- Your rights: you can ask us to confirm whether we hold your consumer health data, to see it along with a list of everyone we've shared it with, to delete it (Delete my account in the app does this, §5), and to withdraw your consent. Email the address in §9 with "Health data request" in the subject. We'll answer within 45 days (we may need to confirm it's you), and it's free.
- Appeals: if we turn a request down, you can appeal by replying with "Appeal" in the subject. We'll answer the appeal in writing within 45 days. If we still say no, you can contact your state's Attorney General (in Washington, atg.wa.gov/file-complaint).
