Memory

Memory stores the reminders you write and the email address you sign in with, so that they follow you from one device to another. That is the whole business. There are no ads, no trackers, no analytics, and nothing is sold or handed to anyone for marketing. You can delete your account from inside the app, and when you do, it is gone.

Who is responsible

Memory is made and run by Juan Antonio Chalita Izquierdo, an independent developer based in Mexico City. Questions about this policy, or about your data, go to memoryapp2026@gmail.com.

What Memory collects

Your account

An email address. If you sign in with a one-time link, that is the address you typed. If you sign in with Google or Apple, that provider gives Memory your email address and an account identifier and nothing else: no contacts, no files, no calendar. Apple's option lets you hide your real address, and Memory works normally with the relay address.

What you put in

• Reminders: the title and notes you write, the date and time, whether it repeats and until when, and whether you have ticked it off.
• Courses: the name, short code and ink you assign.
• Class sessions: the day, the hours and the room.
• Course notebooks (Memory Pro): the notes you write in each course's notebook — titles, text and checklists — and when you wrote them. Photos you add to a note (taken with the camera or picked from your library) are stored privately; only your account can open them, through a link that expires.
• Grades: the grades you write down for each course and period, your grading scale, passing grade and how each period is weighted.
• Class lists and attendance (Memory for Teaching, Memory Pro): if you teach and use Memory for it, the names you add to each group and the attendance you take — present, late or absent, by day. These are names you type yourself; Memory does not contact your students, and they have no account. Only your account can read them, and they go away when you delete the group, the student or your account. You are responsible for having the right to keep your students' names in an app like this one under your school's rules.
• Course materials (Memory Pro): the files you choose to add to a course — a syllabus, a reading, a photo of the board — and the links you save, with their names. Files are stored privately; only your account can open them, through a link that expires after a minute.
• Preferences: your nudge settings, reading density, edition (day or night), your major or school if you entered one, and whether you use Memory to study, to teach, or both.

What the app reads on its own

• Your time zone, read from the device, so that a reminder set for 8am arrives at 8am where you are and not where the server is.
• A notification address, only if you turn notifications on. This is issued by Apple or by your browser's push service and identifies the device, not you. It is stored together with two encryption keys and the device's browser identification string, and is used for one thing: delivering Memory's own reminders.

What Memory does not collect

No location. No contacts or calendar. Memory never reads your photos or files on its own: the only files it has are the ones you pick yourself on a course's Materials tab or add to a note. The camera opens only when you tap the camera button in a note. No advertising identifier. No analytics or crash-reporting kit of any sort is installed in the app. Memory does not track you across other apps or websites, and does not build a profile of you.

Who else touches it

Memory is one person, so it rents its plumbing. These are the only companies involved, and each one only gets what it needs to do its job:

• Supabase (Supabase Inc., United States) stores the database and runs sign-in and the reminder engine. Your reminders, notes, and any course materials or note photos you upload, live here.
• Netlify (Netlify Inc., United States) hosts the web version. Like any web server it keeps ordinary request logs, which include IP addresses.
• Google, only if you choose to sign in with Google.
• Apple, if you use the iPhone app: for Sign in with Apple if you choose it, for delivering notifications through Apple Push Notification service, and for processing Memory Pro purchases. Apple handles the payment; Memory never sees your card or billing details.
• RevenueCat (RevenueCat Inc., United States), only for Memory Pro: it receives your Memory account identifier and the receipt Apple issues for a purchase, and tells the app whether your subscription is active. It does not receive your reminders, notes or files.
• Paddle (Paddle.com Market Ltd., United Kingdom), only if you buy Memory Pro on the web or on Windows. Paddle is the reseller for those purchases: it collects your name, email address, country and payment details to charge you, calculate taxes and send your receipt. Memory never sees your card; Paddle tells RevenueCat which plan you bought, linked to your Memory account identifier.

Because these companies are based in the United States and the United Kingdom, your data is processed outside Mexico. Nobody else receives it. It is not sold, rented, or shared with advertisers or data brokers, and there is no arrangement under which that could happen.

A plain word about notifications

A reminder notification contains the text of the reminder, because a notification that said only "you have something due" would be useless. On the web, that text is encrypted on Memory's server and can only be read by your device. On iPhone, it passes through Apple's push service to reach your lock screen, which is the only way iOS delivers notifications, and Apple's own privacy policy governs that leg.

How long it is kept

Until you remove it. A deleted reminder is deleted. Deleting your account removes every row that belongs to you, every file you uploaded, unsubscribes your devices, and deletes the account itself. Deleting your account does not cancel an App Store subscription: Apple manages that, in your App Store account settings. It is immediate and it cannot be undone, so the app asks you twice.

Deleting your account

Open Settings, go to Account, and choose Delete account. Nothing is retained afterwards except what the law requires. Records of Memory Pro purchases are kept by Apple and RevenueCat under their own policies, as the law requires for payments. If you would rather ask by email, write to memoryapp2026@gmail.com from your account's address and it will be done within 30 days.

Keeping it safe

Everything travels over HTTPS. The database enforces row-level security, which means the rules that decide who may read a row live in the database itself rather than in the app: another signed-in person cannot read your reminders even if the app asked it to. Sign-in is handled by Supabase and Memory never sees a password, because it never asks for one.

Children

Memory is built for university students and is not directed to children under 13. It does not knowingly collect anything from them. If you believe a child has created an account, write and it will be deleted.

Your rights

You can see, correct and delete your data at any time from inside the app, which is the fastest route. You may also ask for a copy of everything stored about you, or ask that it be deleted, by writing to the address above. Depending on where you live these rights come from Mexico's Federal Law on Protection of Personal Data Held by Private Parties, the GDPR, or your local equivalent; the answer is the same either way.

Changes to this policy

Any change is posted on this page with a new date at the top. If a change actually affects what happens to your data, the app will tell you before it takes effect.
