love&truth · privacy
your number, never your words
built so there is almost nothing to collect. a plain-language policy that means what it says.
last updated 30 july 2026
who we are
[LEGAL NAME · COMPANY ID · REGISTERED ADDRESS], trading as DISCISE, Czech Republic — the data controller for everything described on this page. Write to peace@discise.com. We are small enough that the law does not require us to appoint a Data Protection Officer, and honest enough to say so rather than invent one.
what stays on your device
- your diary
- Your book is sealed on your phone and stays there. Its key lives in iCloud Keychain, which is end‑to‑end encrypted — so it reaches your own devices and nobody else, not us and not Apple. The sealed book itself travels in your iPhone’s backup, which is what lets a restored phone open your diary again: whoever else might hold that backup holds a sealed book and no key to it.
- your name
- The name at the head of your book is chosen on your device and stays there. We only ever know your number.
- their names
- When you add someone by number, the name you write for them stays on your phone, yours alone. Our database holds no names at all — not yours, not theirs. Only numbers.
- a letter you keep
- Letters arrive and are gone. If you choose to keep one, it is folded into your diary on your phone. Our server has already deleted it, and the copy that remains is yours alone.
- the face id lock
- An optional veil over the app when you open it. Your face or fingerprint is checked by your phone and never reaches us — we never see it, and never could. It is a convenience, not the thing that guards your words: your diary is encrypted at rest with the lock on or off.
what you share
A page in love&truth is meant to be read by the people you choose, so some of what you write travels. When it does, it is end‑to‑end encrypted on your phone first — sealed to its reader — so the server only ever carries an envelope it cannot open. It holds that envelope for at most 3 days — until every phone it is addressed to has collected it — then deletes it:
- a page to your circle
- Writing today’s page also seals a copy to your circle — the people you have added by number. Your page shows in their circle for those 3 days at most, then falls off the end: the circle is a “today”, with no archive and no history. If you have added no one, the page stays only on your phone.
- a letter to one person
- Sealed to them alone, and deleted the moment their phone confirms it arrived.
In both cases we hold the sealed envelope only in transit, and can never read the words inside.
what we do hold, and why
- your number
- A 6–8 digit number, so the people you give it to can reach you. It is the only name we have for you.
- your connections
- The numbers you have added, so your circle and your letters can be delivered. Numbers only — not names, not content.
- sealed items in transit
- The envelopes described above, held only until delivered, then deleted. The server is a postman, never an archive.
- a report, if you file one
- Reporting someone sends us the last few letters that person sent to you, readable — they have to be, or nobody could act on the report. Everything else here is sealed so tightly that we could not read it if we wanted to; this is the one place where words reach us in the clear, and it happens only when you choose it: only what was written to you, never a line of your own.
- a notification token
- If you allow notifications: an address for this one phone, given to us by Apple, so we can wake it when a letter is waiting. Neither the address nor the notification carries a name, a number or any words — your phone works out who wrote to you, locally, and writes the line itself. Turn notifications off and it is gone.
- your sign‑in
- The service that keeps you signed in records, for each phone, when the account was made, when it last refreshed, and the network address and device type it came from. We never look at it, it is linked to nothing you write, and it goes when you delete your account — but it is there, it is personal data, and a policy that told you otherwise would be lying to you.
That is the whole list. There is no more, by design.
how long we keep it
- sealed items
- Until delivered, and at most 3 days either way. Undelivered is still deleted.
- number, connections
- Until you delete your account, and then immediately.
- a report
- Ninety days, then the report, the letters inside it and the record itself are deleted together — because “this person was reported once, in March” is still a file on somebody, and we keep no files on people.
- notification token
- Until you turn notifications off, change phones, or delete your account.
Nothing here has a long tail. We keep no backups of your words, because we never had your words.
what we never do
- No advertising, ever. No trackers, no analytics SDKs, no third‑party tags.
- No selling, renting, or sharing of any data with anyone.
- No location, no contacts, no microphone, no photo library. The camera is used for one thing only — the day’s drawing, below.
- No public search and no “people you may know”. You are found only by your number, given by hand.
- No read receipts, and no record of who read what — on either side.
- No profiling. Nothing about you is scored, ranked or fed to a model, and no decision about you is ever made automatically. We will never train anything on what you write.
the camera
The camera is here because a diary has always been allowed a drawing in the margin. What the lens sees is turned into a single line on your phone, by the phone’s own graphics hardware. The photograph is discarded the moment the line is made. The drawing is what is kept. Its line is sealed inside your book, like everything else you write — and a picture of it is kept on the phone itself, outside the book, so a page can show it at once. That picture never leaves your phone: it is never uploaded, it is deliberately kept out of your iCloud backup, and your phone encrypts it whenever it is locked.
No photograph is ever uploaded, and none is ever sent away to be redrawn by someone else’s machine. There is no photo‑library access at all: the app cannot see the pictures you already have, and never asks. It is the camera, now, or nothing.
If you choose to send a page to your circle, the drawing goes with it, sealed exactly the way a letter is. Nobody in between can see it, including us.
where it is stored
The little we hold lives with Supabase, in the European Union, with row‑level security on every table so your rows are reachable only through your own authenticated session. Traffic is encrypted in transit (TLS). The account itself is anonymous: there is no email, no password, no phone number.
If you live outside the European Union, that means the little we hold travels into the EU and stays there. This is the opposite of the transfer most policies ask you to accept: we do not move European data out into a weaker jurisdiction — we bring everyone’s under the strictest data‑protection law there is, and keep it there. Where such a transfer needs a legal basis, it is the performance of our agreement with you.
the website
This website sets no cookies, runs no analytics, and loads nothing from anyone else’s server. Nothing about you leaves the page.
paying for it
When love&truth costs money, Apple takes the payment, not us. Apple tells us that a subscription is active and nothing more — we never see your card, your name, your address, or your Apple ID. What Apple does with that transaction is covered by Apple’s own privacy policy, not this one.
encryption, honestly
Letters and shared pages use end‑to‑end encryption built on standard, published cryptography (X25519 and ML‑KEM‑768 for key exchange, Ed25519 for signatures, ChaCha20‑Poly1305, HKDF, SHA‑2). Your keys are generated on your device and never leave it. We have designed this carefully and hold ourselves to a high bar — but no system that touches the real world is ever perfectly secure, and we will never tell you otherwise.
if something goes wrong
We hold so little that the worst realistic breach of our server would expose numbers, and the graph of who added whom — not words, because we do not have the words. If it ever happened we would tell the people affected and the relevant authority, promptly and plainly, and we would tell you what we did not know as readily as what we did.
age
Because love&truth includes private messaging between people, it is meant for older teens and adults. You must be at least the minimum digital‑consent age where you live — for example 16 across much of the EU (some countries set it lower; the Czech Republic sets it at 15) and 13 in the United States. We never knowingly collect data from children below these ages. If you believe a child has an account, write to us and we will delete it.
your rights, wherever you live
What follows is the law in different places. We give all of it to everyone, because writing two versions of a promise is how a promise stops meaning anything. Almost all of it you can do yourself, right now, without asking us: export and delete your account are both in the account menu inside the app. Deletion is immediate and complete — your number, your connection graph, and any sealed items still awaiting delivery are erased. Your on‑device diary is yours to keep or to wipe with the app. For anything else, write to us. We never charge for any of it, and we will never treat you differently for asking.
europe and the united kingdom
Under the GDPR and the UK GDPR you have the right to access your data, correct it, erase it, restrict or object to how we use it, take it with you and withdraw consent at any time. Our lawful basis is the performance of our agreement with you — holding your number and your connections is the only way a letter can find its way — and, for notifications, your consent. There is no legitimate‑interest processing hiding behind this policy, because there is nothing we want to do with your data that you have not asked for.
You may complain to a supervisory authority: in the Czech Republic, the Office for Personal Data Protection (uoou.cz); in any other EU or EEA country, your national authority; in the United Kingdom, the Information Commissioner’s Office.
california
Under the CCPA, as amended by the CPRA, the categories of personal information we collect are identifiers (your number, the numbers you have added, and a notification token if you allow notifications) and user content (sealed pages and letters, in transit only, which we cannot read). We collect them for one business purpose: to deliver what you asked us to deliver. We collect no sensitive personal information and infer nothing from anything.
We have never sold or shared personal information, and never will. There is no “Do Not Sell or Share My Personal Information” link on this site because there is nothing to opt out of. You have the right to know, delete and correct; the right to opt out of sale, sharing and targeted advertising, none of which occur; and the right not to be discriminated against for exercising any of them. An authorised agent may act for you, with proof.
the rest of the united states
If you live in Virginia, Colorado, Connecticut, Utah, Texas, Oregon, Montana, Delaware, Iowa, Nebraska, New Hampshire, New Jersey, or another state with a consumer privacy law, you have the same rights and we give them the same way. We do not sell personal data, do not use it for targeted advertising, and do not profile anyone. You may complain to your state Attorney General, or to the Federal Trade Commission.
everywhere else
Brazil (LGPD), Canada (PIPEDA), Australia, Japan (APPI), South Korea (PIPA), Switzerland (FADP) and the rest: the same rights, exercised the same way, with the same regulators available to you if we fall short. And in general — where the law where you live gives you a right this policy has not named, you have it. We would rather be bound by all of them than argue about which one applies.
changes
If this policy ever changes, we will update the date above and, for anything that matters, tell you in the app before it takes effect.
