Privacy Policy
Last updated October 7, 2026
This policy explains what Elio collects, why, who processes it for us, and the choices you have. Elio is provided by Jeffrey Ngare, a sole proprietor based in Texas, United States. Contact: support@studywithelio.com.
We do not sell your personal information, we do not show ads, and we do not use advertising or analytics trackers.
What we collect
Account
When you sign in with Google, we receive your email address and a Google account identifier. We do not request your contacts, calendar or other Google data. If you add a second email address to your account, we send it a verification link. The name and profile photo you add during setup are stored with your account and shown only to you.
Study data
What you do in Elio: your answers and attempts, time on questions, review schedule, progress and readiness history, notes, cards you create, files you upload, your exam date and goals, scores you choose to enter, and your settings. This data is stored on your device so Elio works offline, and synced to our database so it follows you across devices.
AI requests
When you use an AI feature, such as the tutor, the coach or a file upload that Elio reads for you, the text of your request and the study context it needs are sent to an AI provider to produce the answer. We keep a record of each AI request with its cost, so we can apply your AI allowance.
Device information
For each device you use, we record a device class (phone, tablet or desktop), whether Elio runs as an installed Home Screen app or in a browser tab, when the device was last seen, and how long its first sync took and how often it paused. We use this to decide which devices to support better. We do not record your browser's user agent string, and none of this includes the content of your study.
Payments
Paddle processes payments as our reseller and Merchant of Record. We never see or store your card details. Paddle tells us your plan, its status and dates, and Paddle's customer and subscription identifiers, so we can unlock your plan.
Reminders and notifications
Elio keeps an inbox of notices in the app, such as your daily plan reminder, a new sign-in to your account, or reaching your AI allowance, and deletes each one after 90 days. If you turn on push notifications on a device, your browser gives Elio a subscription for that device: a web address at your browser's push service (Apple, Google or Mozilla, depending on the browser) and two encryption keys. We store those, with the device's browser name, your reminder time, quiet hours, time zone and which kinds of notices you want, so we can send the notices you chose to that device and nothing else. The push service receives only an encrypted message for your device; we use no other notification provider. You can turn push off for a device or pause all notices in Settings, Notifications, or block Elio in your browser's site settings; we delete a device's subscription when you turn it off there or when the push service tells us it is no longer valid.
Technical data
Our hosting providers process your IP address and request details to deliver and protect the service. The Fly.io gateway at app.studywithelio.com writes a log line for each request, including your IP address, and Fly.io keeps those logs for up to 7 days. Elio's database does not store your IP address.
Access requests
If you ask for access to the beta, we store your name, your email address, your exam month and the one line you write in a free-text box, so we can decide whether to invite you and contact you about it. We keep a request until you are invited or declined, and delete it within 90 days after that; email us to have it deleted sooner. We do not use it for marketing. Neon stores it for us. For a new request, Resend sends the owner a notice with your name, email address and exam month, at most ten notices a day; the line you write stays in the database, and Elio stores no IP address with a request. While you fill in the request form, this website keeps what you typed in your browser tab's session storage, so a request that comes back unsent can be sent again without retyping. That copy never leaves your device, and it is removed when the request is received.
How we use it
- to run Elio for you: sign you in, sync your study record, and choose and schedule your work;
- to answer AI requests and apply your AI allowance;
- to unlock and manage your plan;
- to keep Elio secure, prevent abuse and fix problems;
- to send the emails the service needs, such as sign-in and verification links.
Who processes it for us
We share personal information only with the providers below, and only for the purpose listed.
| Provider | What for | What it receives |
|---|---|---|
| Cloudflare | Hosting the app, security | Requests to the app, IP address, sign-in email |
| Fly.io | Hosting this website, studywithelio.com, and routing requests to the app at app.studywithelio.com | Requests to this website and the app, IP address |
| Neon | Database | Your account and study data |
| Sign in with Google | The sign-in request | |
| Anthropic | AI tutor, coach, question generation and upload reading | The text of AI requests and the study context they need |
| OpenAI | Drafting practice cards | The source material being turned into a card |
| DeepSeek | Drafting practice cards | The source material being turned into a card |
| Paddle | Checkout, payments, tax, refunds | What you enter at checkout |
| Sentry | Error reports, so we can find and fix problems | The error message and where in Elio it happened, with email addresses, account identifiers and sign-in tokens removed before it is sent, and the app version. Your IP address reaches Sentry with each report; Sentry is set not to store it, or any location worked out from it. |
| Resend | Sending sign-in and verification emails | Your email address and the message |
| ImprovMX | Forwarding email you send to support@studywithelio.com | Your email address and the message |
These providers process data in the United States and in other countries where they operate. AI providers process requests under their API terms. We may also disclose information if the law requires it.
Who at Elio can see your data
Elio is run by one person, the owner named above. No screen in the app shows one learner's study data to another person, the owner included. The owner can reach the database directly to run the service, and does so only to fix a problem, to answer a request you make, to keep the service secure, or when the law requires it. The owner does not browse accounts, and does not use your study data for anything other than running Elio for you.
Everything in your account is kept separate from other accounts by the database itself, not only by the app, so one learner's request cannot return another learner's rows.
Cookies and local storage
Elio uses cookies only to keep you signed in and to protect sign-in. It stores your study data in your browser's storage so it works offline. This website sets no cookies of its own. The checkout page loads Paddle's checkout, and Paddle may use cookies or browser storage there to process your payment and prevent fraud, as its privacy notice describes.
How long we keep it
We keep your account and study data while your account is open. When your account is deleted, we delete your study history, plans, notes, progress, AI tutor history, device information and sign-in addresses from our database. After that, the same email address can be used to open a new account.
We keep only a deletion record that contains no email address and no study content: a one-way scrambled form of your account number and a count of the rows removed, so we can show the deletion happened.
Some copies last longer, outside our control or yours:
- our database provider keeps backups for up to 35 days, so deleted data can remain in those backups until they expire; if we ever restore from a backup, we delete again any account that was deleted before the restore;
- Paddle keeps its own customer and payment records as the Merchant of Record, under its own policies;
- any export file you downloaded stays wherever you saved it.
Your choices
- Export: download your study data at any time from the Data page in the app.
- Correct: change your settings and profile in the app, or ask us.
- Delete: in Settings, Account, schedule your account for deletion by typing the confirmation shown. Deletion happens 7 days later, and you can cancel it at any time before then. If you have an active paid plan, cancel it first under Manage billing; if you have already canceled, you can delete once the paid period ends. You can also email support@studywithelio.com from your account's address, and we will complete the deletion within 30 days. Data already on your own devices stays there until you clear it.
Depending on where you live, you may have further rights, such as to access your data or object to how it is used. Email us and we will respond within the time the law requires.
Age
Elio is for people 18 and older. We do not knowingly collect information from anyone under 18. If you believe a child has an account, contact us and we will delete it.
Security
Your study data is separated per account in the database, connections are encrypted, and access is limited to what the service needs. No system is perfectly secure; tell us at the address above if you find a problem.
Changes
We will post any change here with a new date, and tell you in the app or by email before a material change takes effect.
