App: Lembrô (com.damcode.lembro)
Last updated: 13 August 2026
This is a translation, provided for convenience. Lembrô is developed in Brazil and these
terms are governed by Brazilian law. If the two versions ever disagree, the
Portuguese version is the one that prevails.
1. What Lembrô is — and what it is not
Lembrô is a tool for organising and remembering things you do again and again: taking
medicine, drinking water, measuring blood pressure, walking, changing a dressing.
Lembrô is not a medical device. It does not diagnose, treat or prescribe, it does not
calculate doses, it does not interpret any health data and it issues no clinical
recommendation. It records that you did a task, at the time you did it — nothing beyond
that. There is no way to write down values such as blood pressure, blood sugar or weight, by
product decision.
Lembrô does not replace your doctor’s guidance, the medicine’s leaflet, the prescription or
the care of a health professional. If what is in the app conflicts with what the professional
told you, the professional’s guidance is the one that counts.
By using the app you agree to these Terms, which are available at any moment inside the app,
under Settings → About, and on this page. If you do not agree, do not use it.
2. Your responsibility when using it
You are responsible for:
Entering correctly the names, times, days and repetition of each reminder. The app
notifies you at the time you chose; it does not know which time is the right one.
Keeping the system permissions active, notifications in particular. If you deny or revoke
that permission, the app keeps working, but it stops notifying you.
Keeping a backup, if the history matters to you. The data lives only on your device:
losing or wiping the phone without a saved backup means losing the history, and we have no way
of recovering it.
3. About notifications: what can be late, and what we do not guarantee
This is the most important part of these Terms, and it is written without hedging:
Notifications are scheduled on your phone, by the operating system. They can be late, and
they can fail for reasons beyond our reach: battery saving, aggressive optimisation by the
manufacturer, “force stop” on the app, a phone that is switched off, out of battery, in
aeroplane mode or with notifications silenced.
You can reduce the delay by granting two permissions, and the app works without either of
them:
“Alarms and reminders” makes the time be honoured without the system adjusting it.
Without it, Android batches notifications to save battery and the delay can exceed a few
minutes — especially with a phone that has been idle for hours.
“Full screen” lets the Alarm level appear over the lock screen. Without it, the same
notification still rings with the alarm sound, only as a notification.
Both are granted by you, in your phone’s settings, and can be withdrawn at any moment. The app
shows on the home screen which one is missing.
The Alarm level is your choice, reminder by reminder: it rings with the device’s alarm
sound until you turn it off, snooze it or record. The other three levels notify you as an
ordinary notification. None of this changes the notification of reminders you already have —
the default is still the discreet one.
Even so, the notification is reliable, not infallible. No permission stops your phone’s
manufacturer from killing the app in the background.
For critical medication, keep a redundancy. A second alarm on a clock, a weekly pill
organiser, or another person reminding you. Do not use Lembrô as the only barrier between you
and a dose that cannot be missed.
We do not guarantee uninterrupted operation or the absence of faults.
4. NFC tags
NFC tags are optional. The app works fully without them: the button on the card records
everything. If you do use tags:
They are ordinary stickers, bought by you from whoever you choose. Tags bought from third
parties are the responsibility of the seller you chose.
The app points, in the tag explanation, to a kit sold by the developer through an external
store (Mercado Livre). Buying it is optional and happens outside the app. In that sale we
answer as supplier, under Brazil’s Consumer Protection Code: a 90-day legal warranty against
defects (art. 26, II), replacement of the defective tag, and the delivery time stated in the
listing. The price is the one in the listing at the time of purchase. The sale and delivery
of tags serve Brazil only.
The tag holds only a random identifier created by the app, never health data — see the
Privacy Policy.
Reading a tag requires the phone’s NFC to be switched on and the device to have NFC. Not every
phone does.
The “tag only” option makes recording require the sticker. If you lose or damage the tag,
switch that option off in the reminder’s settings to go back to recording with the button.
5. Free plan and paid plan
Lembrô is free and functional. These never depend on payment: creating as many reminders as
you want, receiving the notifications, recording (by button or by tag), using the app without an
internet connection, and saving a full backup.
All notification levels are free, including insistent and alarm. Insisting is the strongest
form of notifying, and being notified never depends on payment.
Full Lembrô is optional and unlocks three things: unlimited tags, history visible beyond the
last 30 days, and the period summary. If the plan expires, nothing is deleted: what you have
already created keeps working and recording, and the full history stays on the device and in the
backup.
Being followed by a carer is a separate subscription (“Follow someone”), paid by the
person who follows — the person being followed never pays for it. About it:
It depends on an internet connection on both devices and on cloud infrastructure (Google
Firebase), described in the Privacy Policy. It only exists with the explicit
authorisation of the person being followed, who can remove it at any moment.
The panel shows what was recorded in the app, not what actually happened, and the “past
its time” highlight appears when the app is opened — it is not a real-time alarm, and it
must not be anyone’s only form of care.
If the subscription expires, the pairing is not undone: the panel becomes unavailable and
comes back when the subscription does. Nothing is deleted.
The prices shown come from the app store itself, in your country’s currency.
6. Liability
We do not cap our liability at any amount. Brazil’s Consumer Protection Code treats as void
any clause that excludes or reduces the supplier’s liability (art. 51, I), and it would make no
sense to write here something the law already strikes down — nor would it be honest with whoever
is reading.
Our liability is the one Brazilian law determines, to the extent that it determines it.
What is not our obligation, because it is not under our control:
the workings of the operating system, of the device or of the manufacturer’s optimisations;
the delivery of notifications by the system, in the situations described in item 3;
the quality, durability and functioning of NFC tags you bought from third parties;
the availability of the devices’ internet connection and of the carer feature’s cloud
infrastructure, operated by Google (item 5);
the loss of data when the device is lost, wiped or replaced without a saved backup — we
have no access to your data and therefore have nowhere to recover it from;
health treatment decisions, which are for you and your health professional, as per item 1.
Nothing here sets aside rights that the Consumer Protection Code guarantees and that cannot be
waived.
7. Purchases, renewal, cancellation and withdrawal
Payment is processed by the app store (Google Play or the App Store), acting as seller. We
do not receive or store your payment data.
Subscriptions renew automatically until you cancel. Cancelling is done in the store
itself, and you keep access until the end of the period already paid for.
Free trial: the “Follow someone” subscription has 7 free days the first time, applied and
charged by the store itself — at the end of the period, billing starts on its own if you do not
cancel first. The store shows the exact date on the purchase screen.
The one-time purchase does not renew and does not expire. It is valid for the app on the
store account it was made with, including when you change devices, for as long as the app
exists and is distributed by the store — see item 11.
Right of withdrawal: purchases made at a distance can be undone within 7 calendar days,
under article 49 of Brazil’s Consumer Protection Code. The refund request is processed by the
store, which has its own policy — if it refuses a request within that window, talk to us using
the contact below.
Where your country’s law grants more, your country’s law applies. The 7 days above are the
minimum under Brazilian law. If you bought from a country whose consumer law gives a longer
window or an additional right, that one prevails — nothing written here reduces what the law of
your domicile guarantees.
8. Who can use it
The app is intended for people aged 18 and over, and it is not directed at children or
teenagers. A responsible adult may create reminders relating to a dependant, remaining
responsible for what they enter and for the data on their own device.
9. Changes to these Terms
If these Terms change in a relevant way, we will give notice before the change takes effect,
through this page and the store’s channels, with the date at the top changed. Changing a rule
silently is exactly what this app does not do.
In particular: if any future version begins sending data off the device, that will be announced
beforehand, will require your specific consent on screen, and will never be switched on by
default.
10. Applicable law and jurisdiction
These Terms are governed by Brazilian law. For consumers, the courts of their own domicile are
assured, under the Consumer Protection Code, regardless of any provision to the contrary.
Outside Brazil, this does not set aside the consumer protection rules of your country of
domicile that cannot be waived by contract. Choosing Brazilian law is there to give everyone a
single text to read, not to take anyone’s rights away.
11. If the app is discontinued
Software does not last forever, and promising eternity would be a promise nobody can keep. So
here is what happens, in writing:
If we decide to end Lembrô, we will give notice at least 30 days in advance, through this
page and the store’s channels.
No new charge will be made from the notice onwards, and ongoing subscriptions will be
stopped in the store.
The app already installed keeps working on your device: it depends on no server of ours,
and on no internet connection, to remind and to record.
Before the shutdown, save a backup. It is the file that preserves your reminders and your
history, and it is yours — in an open format, readable without the app.
Anyone who bought access through a one-time payment and is affected by a shutdown close to
the purchase may request a refund through the contact below, in addition to whatever the
store’s policy already offers.
