Privacy Policy

Last updated: September 29, 2026

Nightsesh ("Nightsesh", "we", "us") is an AI study platform for iPhone, iPad and Mac, made by Sparks Strategies LLC. You can study by chat (Chat study), by talking out loud (Voice study), by listening (Walk & study), and by recording your classes and turning them into notes. This policy explains what information Nightsesh collects, why, who helps us process it, how long we keep it, and the choices you have. We wrote it in plain English. If anything is unclear, email us at [email protected].

The short version

Nightsesh is for students 13 and older. We don't knowingly create accounts for children under 13.
No ads. We don't sell your information, don't share it for advertising, and don't track you across other companies' apps or websites. Nightsesh has no third-party advertising or analytics code.
We collect what we need to run Nightsesh: your sign-in, the study material you add, your notes, cards and progress, your chats, and your purchases.
Nightsesh's AI uses Anthropic (text and images) and OpenAI (voice). Class recordings, board photos, scanned pages and dictation are turned into text on your device. The audio and pictures aren't uploaded.
We don't train AI models on your information, and our AI providers don't either.
You can delete your account and data at any time in the app: Settings › Account › Delete account.

1. Who this policy covers

This policy covers the Nightsesh apps (including test versions in Apple's TestFlight), the Nightsesh service behind them, and these web pages. It doesn't cover Apple's App Store, Sign in with Apple, Siri, or other companies' apps and websites. Their own privacy policies apply.

2. Age requirement

You must be at least 13 to use Nightsesh. Before you sign in, Nightsesh asks you to confirm you're at least 13, and we record the time you did. We don't ask for your birth date. Nightsesh isn't directed to children under 13, and we don't knowingly collect personal information from them. If we learn that someone under 13 has an account, we'll delete it and its data. If you're a parent and think your child under 13 is using Nightsesh, email us and we'll delete the account.

If you're 13 to 17, please use Nightsesh with your parent or guardian's knowledge. Purchases go through Apple, where a parent can approve them with Ask to Buy.

3. What we collect

Information you give us

Information	Details
Account	Your Sign in with Apple account ID, and your email address if you choose to share it (Apple may give us a private relay address instead). The time you confirmed you're 13 or older. Whether AI study help is on, and when you turned it on.
Study material in your Subjects	Notes you type or paste, study guides, and document files (such as PDF, Word, PowerPoint, Excel and EPUB). We keep original document files so you can open them again. For photos of notes, scans and handwriting, only the text read on your device is uploaded, not the picture. For recordings, only the transcript is uploaded, not the audio. Material is uploaded only after you turn on AI study help.
What Nightsesh makes from it	Outlines, topics, study cards, explanations and citations (such as "Slide 12"). Cards you write yourself.
Chat study	Your questions and the AI's replies, saved with the Subject. If you attach a photo (for example, of your work), it's sent to our AI provider for that reply only. We keep only a fingerprint (a hash) of the photo, not the photo itself. Chat study also keeps a few short "reminders" (for example, "found photosynthesis tricky") that expire on their own (see section 8).
Class notes	If you're signed in, your notes sync to your study account so your other devices show them: titles, sections, earlier versions, your jots and marks ("This matters", "Lost me"), the class transcript, and the text read from board photos and slides. Audio, board photos, slide pictures and photos in your notes stay on the device that took them. Only their file names sync, so other devices can show that they exist.
AI requests about your notes	When you use Make my notes, ask the AI to change a note, Quiz me, ask a question across your notes, or search your notes by meaning, the content that request needs is sent to our AI provider. We keep a record of each request with its result and a fingerprint of what was sent. That way a dropped connection doesn't lose your notes and you're never charged twice.
Walk & study	To make a walk, we send the Subject's name, your topics and how well you know them, some of your cards, and short excerpts from your material. We keep the finished script. The spoken audio is made from the script and downloaded to your device so it plays without a signal.
Voice study	See "Live voice" below. We store how many voice seconds you used and when.
Study progress	Your answers, whether they were right, timing, mastery, exam dates and goals.
Sharing	If you share a Subject or join one, see section 7.
Friend invites	If we offer friend invites and you use one, we record your invite code, who invited whom, and a random install ID (so a code can be claimed only once per device).
Feedback and reports	What you send through "Report a problem", "Share an idea", or Report on a card or reply, and what it's about. Unless you switch it off in the report, we also get the app version, device type (such as "iPhone"), system version, the screen you were on, your language setting and recent error messages.
Purchases	From Apple's signed purchase records: which plan or voice pack, purchase and expiry dates, free-trial status, refunds, and Apple's transaction IDs. We never see your card or payment details.
Support emails	What you write to us and your email address.

Live voice

Voice study is a live conversation. While a call is on, your microphone audio and the lesson on screen go straight from your device to OpenAI. Our server only starts and ends the call and counts its length. If you ask about your notes during a call, Nightsesh looks them up on your device and sends the matching passages into the conversation. OpenAI also turns what you say into text, so the app can show crisis support if you say something worrying (section 12). That text is used on your device and isn't saved. We don't record or store call audio or transcripts.

Information collected automatically

Information	Details
Usage and limits	How much AI help, class-notes time and voice time you use, to apply plan limits and prevent abuse.
Usage counts	Simple first-party events: install, first material added, first cards, first reply, plan screen seen or closed, voice taste used, trial started, paid, a once-a-day "active" mark, and review prompt shown. Each comes with a random install ID the app makes, your platform (iOS, iPadOS or macOS) and the time. They contain no study content, go only to our own server, and are never shared. You can turn them off: Settings › Help make Nightsesh better › Share usage counts.
Apple Ads attribution	If usage counts are on and you installed Nightsesh from an Apple Ads ad, Apple can tell us which of our campaigns it was. The app gets a one-time token from Apple, and our server exchanges it with Apple. We keep only whether an ad was involved, the campaign, ad group and keyword IDs, and the country or region. This doesn't use your advertising identifier and doesn't identify your device.
Technical data	Like any online service, our servers receive your IP address and basic request details. Our own servers log only warnings and errors, never your sign-in token. Our hosting and database providers keep technical logs, which can include IP addresses, for a short time (currently 7 days or less). Our sign-in provider records sign-in events for security.
TestFlight	If you test a beta through Apple's TestFlight, Apple gives us the name and email you were invited with, and any crash reports, feedback and screenshots you choose to send. Apple's TestFlight terms apply.

We don't collect your location, contacts, advertising identifier (IDFA), browsing history, health data, or voiceprints or other biometric identifiers. Nightsesh doesn't read other apps or your screen.

4. What stays on your device

Class recordings are saved on your iPhone, iPad or Mac and turned into text there by Apple's built-in speech recognition. That includes the live transcript, captions and "Catch me up" while you record. The audio is never uploaded, including recordings you import.
Board photos, slide pictures and photos you add to notes are read on your device by Apple's text recognition. The pictures stay on the device. The text read from them becomes part of your notes.
Photos of notes, scans and handwriting you add to a Subject are read on your device. Only the text is uploaded.
Dictation uses Apple's speech recognition on your device.
Small helpers that suggest a Subject name, reword an explanation more simply, or turn a search into likely terms run on Apple Intelligence on your device, where it's available.
Caption translation uses Apple's translation on your device.
Spotlight and Siri: your notes are indexed on your device so Spotlight can find them. When you use Siri or Shortcuts, Apple's privacy policy covers what you say to Siri.
Study reminders are scheduled on your device.
A copy of your Subjects, notes and progress is kept on your device so you can study offline.

What's stored on your device stays there until you delete it or delete the app. It may be included in your device or iCloud backups, which Apple's policies cover.

5. How we use information

To run Nightsesh: sync your material and notes, make cards and notes, answer your questions, run voice calls and walks, and apply plan limits.
To keep Nightsesh safe: apply our teen safety rules, show crisis support, review reports, and prevent abuse and fraud.
To handle purchases and support requests.
To fix bugs and improve Nightsesh, using feedback you send, error logs, and totals from usage counts. We never use it to build advertising profiles.

We don't look through your study material, notes or chats. We see them only when you send them to us in a report or support request, when we need to fix a problem you've asked us to fix, to investigate abuse or a safety concern, or when the law requires it.

We don't use your information for ads. We don't sell it or "share" it (as California law defines "share"). We don't use it for profiling that has legal or similarly significant effects on you. We don't train AI models on it, and our AI providers don't either (section 6).

6. Who helps us (service providers)

We use a small number of companies to run Nightsesh. They may use your information only to provide their service to us.

Company	What they do	What they receive
Anthropic (Claude)	AI for Chat study replies (including attached photos), turning your material into outlines and cards, checking photos of your work, making and changing notes, Quiz me, answering questions across your notes, search by meaning, and writing Walk & study scripts	The material each request needs, plus our safety instructions. Anthropic doesn't train its models on this data. It deletes API inputs and outputs within 30 days. If its automated safety systems flag a request as breaking its Usage Policy, it may keep that request for up to 2 years (Anthropic).
OpenAI	Voice study, and reading Walk & study scripts aloud	During a call: your microphone audio, the lesson on screen, and passages from your material that the voice looks up. For walks: the script text. OpenAI doesn't train on API data by default, and it keeps abuse-monitoring logs for up to 30 days (OpenAI).
Supabase	Database, file storage and sign-in (United States, Virginia)	Your account, study material and files, notes, cards, chats, progress, usage counts and purchase records
Fly.io	Runs our servers (United States, Virginia)	Everything our servers process, while they process it
Apple	Sign in with Apple, App Store payments, Apple Ads attribution, TestFlight	What's described above. Apple's Privacy Policy covers what Apple itself collects.
Google (Google Workspace)	Our support email	Messages you send us

Before any of your material goes to an AI provider for the first time, Nightsesh asks you. You can turn AI study help off at any time in Settings › AI & privacy. Turning it off stops new AI requests and ends an active voice call. It can't recall material that was already processed. You can still study the cards and notes you already have.

We may also disclose information:

if the law requires it (for example, a valid court order)
to protect someone's safety
to investigate or prevent abuse or fraud
as part of a business transfer (for example, a merger or sale), in which case this policy would still apply to your information
when you ask us to (for example, when you share a Subject)

On plans that include sharing, you can share a Subject's cards with classmates you approve:

You publish the Subject and send an invite link. Links expire.
Someone who opens the link asks to join and gives a display name, which you see. You decide who gets in.
People you approve see the Subject's title and its cards: questions, answers, explanations, topic names and citation labels (such as "Slide 12"). They don't see your original files, notes, recordings, transcripts, chats or progress, and they don't see your name or email.
Their own progress on your cards is saved to their account.
You can remove someone at any time. After that, they can't get the Subject from our service. They can report a shared Subject and block the person who shared it.

8. How long we keep information

While your account is open, we keep your study material, files, notes, cards, chats, progress, usage records and purchase records so you can use them.
Deleting things yourself: deleting a Subject deletes it from our database, along with its material, cards, chats and progress. Deleting a note removes its content from our servers. A small marker stays so the deletion reaches your other devices. The saved result of each notes request is kept until you delete your account.
Chat study reminders expire automatically and are then deleted: open questions after 7 days, practice gaps after 30 days, and study preferences after 60 days. New evidence restarts the clock. You can clear them any time: Settings › AI & privacy › Clear what Chat study remembers.
Usage counts and Apple Ads attribution are kept while your account is open and deleted with it.
Feedback and reports are kept while your account is open so we can follow up and track fixes.
When you delete your account, we immediately delete from our live systems your sign-in record, profile, uploaded files, Subjects, study material, cards, chats, reminders, notes, notes requests, progress, usage records, usage counts, attribution, feedback, invite records, and purchase and balance records. Anyone you shared a Subject with loses access to it.
- Our database provider may keep backup copies. Any copies are removed as its backups roll over, within 30 days.
- Technical logs expire on their own, currently within 7 days.
- Our AI providers keep request data only as described in section 6.
- Apple keeps its own purchase records.
- Copies on your own devices stay until you delete them or the app.
We may keep limited information longer if the law requires it, or to resolve a dispute, prevent fraud or enforce our Terms.

9. Your choices and rights

Delete your account: Settings › Account › Delete account in the app. You can also email us. Deleting your account doesn't cancel an Apple subscription. Cancel it in your Apple Account settings.
Turn AI study help on or off: Settings › AI & privacy.
Clear what Chat study remembers: Settings › AI & privacy.
Turn off usage counts (and Apple Ads attribution): Settings › Help make Nightsesh better › Share usage counts.
See, correct or get a copy of your information: email us. We'll reply within 45 days. If we need more time (up to 45 more days), we'll tell you why.
Parents and guardians of a user under 18 can contact us to ask what we have, get a copy, or have their teen's data deleted.

We'll take reasonable steps to confirm that a request really comes from you, or from someone you've authorized. For example, we may ask you to write from the email address on your account or to confirm something only you would know. We use what you give us for this only to handle the request.

U.S. state privacy rights

Depending on where you live (for example California, Colorado, Connecticut, Delaware, Maryland, Oregon, Texas or Virginia), you may have the right to:

know what personal information we have about you and access it
correct it
delete it
get a copy in a portable format
opt out of the sale of your information, targeted advertising, and profiling that has legal or similarly significant effects (we don't do any of these)
not be treated differently for using your rights

To use these rights, email [email protected]. You can also have an authorized agent send a request for you. We may ask the agent for proof that you gave permission, and we may ask you to confirm your identity with us directly.

Appeals. If we turn down your request, in whole or in part, we'll explain why. You can appeal by replying to our answer or by emailing us with "Appeal" in the subject line. We'll answer your appeal in writing within 45 days and explain what we decided and why. If you disagree with the result of your appeal, you can contact your state's attorney general. For example, Colorado residents can go to coag.gov, Connecticut residents to portal.ct.gov/ag, and Virginia residents to oag.state.va.us.

Teens

We don't sell teens' information, don't show them targeted ads, and don't profile them for decisions with legal or similarly significant effects. This goes for every user, whatever their age.

Global Privacy Control and "Do Not Track"

We don't sell or share personal information and don't track you across other sites or apps, so there's nothing to opt out of. If your browser or device sends a Global Privacy Control signal, we'll treat it as a request to opt out of sale and sharing, just in case.

California

Categories. In the past 12 months we've collected the categories below. We got them from you, from your device, and from Apple (sign-in, purchases, Apple Ads attribution). We use them for the purposes in section 5 and disclose them only to the service providers in section 6:
- identifiers: Apple account ID, email address, IP address, random install ID
- commercial information: plan and purchase records
- internet or other electronic activity: usage counts, usage and limit records, technical logs
- audio: your voice during a live voice call, streamed to OpenAI and not stored by us
- inferences about your studying: mastery and Chat study reminders
- the content you add: study material, notes, chats, feedback
No selling or sharing. We haven't sold or shared personal information in the past 12 months, including that of consumers under 16.
No sensitive-information inferences. We don't use sensitive personal information to infer characteristics about you.
Retention. We keep each category for the periods in section 8.
"Shine the Light." We don't disclose personal information to others for their own direct marketing.
Users under 18 in California can remove content they've posted on Nightsesh. Delete it in the app (for example, stop sharing or delete the Subject), or email us to ask us to remove it. Removing it from Nightsesh may not remove copies others already made.

10. Security

Connections to Nightsesh are encrypted (HTTPS/TLS).
Data is stored with a provider that encrypts it at rest.
Database rules limit each account to its own data.
Keys for our AI providers stay on our servers, never in the app. Voice calls are set up by our server, and the app only gets a handle for its own call.
Sign-in tokens are kept out of our logs.

No system is perfectly secure. If a breach affects your information, we'll notify you and the authorities as the law requires.

11. Nightsesh's AI

Chat study, Voice study and Walk & study are powered by Nightsesh's AI. It's AI, not a person, and it can make mistakes. Nightsesh shows where answers came from in your material so you can check.
Every AI request includes safety rules we wrote for teens.
Nightsesh's AI doesn't make decisions about you that have legal or similarly significant effects.

12. Safety features

If a message you type, or something you say in Voice study, suggests you may be in danger, Nightsesh shows support right away: call or text 988 (Suicide & Crisis Lifeline), or call 911 in an emergency. The AI is also told to respond with those numbers.
This check runs on your device. It doesn't notify anyone, including your parents, your school or emergency services, and it never blocks studying.
We review reports sent through the app to keep Nightsesh safe.

13. Where we operate

Nightsesh is offered in the United States. We and our database and hosting providers store and process information in the United States. If you use Nightsesh from somewhere else, your information will be transferred to the United States.

14. Changes to this policy

If we change this policy, we'll update the date at the top. If a change is important, we'll tell you in the app before it takes effect. If we ever want to use your information in a way this policy doesn't allow, we'll ask you first.
