LLort
Anti-spam community App

LLort needs to be your default phone app to do its job. Android only grants incoming call interception, spam detection before the phone rings, and the ability to display the incoming call screen to the app that is designated as the default dialer.

Without this designation, LLort can still function as a contacts and call log viewer, but it cannot screen calls, block spam automatically, or show its interface when someone calls you.

You can change the default dialer at any time in Android Settings → Apps → Default apps → Phone app.

LLort replaces your default phone app, which means it needs access to the same permissions any dialer requires: reading contacts, making and managing calls, reading call logs, sending and receiving SMS.

Additionally, some features require specific permissions:

• Drawing over other apps — to display the incoming call screen on top of whatever you are doing
• Notification access — to detect and filter spam notifications
• Do Not Disturb — to silence unknown callers automatically

None of these permissions are used to collect personal data. They are purely functional. You can review them at any time in Android Settings → Apps → LLort → Permissions.

This problem occurs when your phone does not support icon customization. Go to the LLort settings menu via the Android settings panel. Once in the app, go to the color customization menu and choose a dark or light system theme. If this does not change anything, it will probably be necessary to reinstall the application.

• Version installed from the Google Play Store
Updates are delivered automatically by the Play Store. There is nothing to do and no special permission is required.

• Version downloaded directly (outside the Play Store)
Two permissions are required to download and install an update through the application: permission to access the phone's storage, and permission to install third-party applications. Go to Android Settings → Apps → LLort → Permissions and verify that these two permissions are allowed for LLort.

This almost always comes down to a missing permission. Here is what to check:

• LLort must be set as your default phone app — without this, it cannot display its screen when a call arrives.
• Display over other apps must be enabled — this allows LLort to appear on top of your screen during a call.
• Background activity must be allowed — LLort needs to stay active even when you are not using it.
• Notification access must be granted.

In most cases, enabling "Display over other apps" solves the problem immediately. Open Android Settings → Apps → LLort → Permissions to check.

This is almost always a permissions issue. LLort needs specific authorizations to display your contacts, call history, and messages:

• Read contacts — allows LLort to access your address book.
• Read call log — allows LLort to display your recent calls.
• Read SMS / Receive SMS — allows LLort to display your messages.

Check Android Settings → Apps → LLort → Permissions and make sure all relevant permissions are granted.

If permissions are already granted and a list is still empty:

• Go to Settings → Contacts → Force resync contacts
• Go to Settings → Calls log → Force resync calls log
• Go to Settings → Messages → Force resync messages

Note: contacts stored only on your SIM card may not appear — Android does not always expose SIM contacts to third-party apps.

LLort does not replace your default contacts application — we let the system manage the creation or modification of your contacts. There is therefore a slight delay before the information reaches LLort. However, we do not exclude the possibility of one day taking over contact creation and editing for users who want it.

By default, LLort simply filters notifications: it only alerts you to trusted notifications and does not manage your messages — which is why, in this mode, it cannot mark them as read from notifications.

If you want full message management (reading, sending, MMS, marking as read…), simply set LLort as your default SMS app in the settings. The choice between simple filtering and full management is yours.

The Countermeasure button is LLort's way of sending spammers a message they won't soon forget — in music.

When you receive a suspicious call and activate it, LLort fires off a sequence that blasts a rather striking sound directly into the caller's ear — the kind that politely but firmly suggests they never dial your number again. At the end of the sequence, the number is automatically blocked and reported to the community database, so other users benefit too.

Think of it as a one-way concert: you set the tone, they get the message.

Important: only use the Countermeasure on calls you are certain are malicious. Using it on a legitimate caller would be disrespectful and inappropriate. LLort will always ask for your confirmation before initiating the sequence.

There are several ways to block in LLort:

• From an incoming call — tap the block option directly on the incoming call screen.
• From the call log — long-press on any entry and select "Block & report".
• From a message thread — long-press on a message and select "Block & report".
• From the contacts list — long-press on a contact and select "Block contact". Note: this blocks all phone numbers associated with that contact.
• From the blocked numbers list — go to Settings → Blocked Numbers → Add manually.

When you block a number, it is added to your personal block list and reported to the community database so that other users benefit too.

False positives can happen. What you can do depends on why the number was blocked.

If the number was blocked by the community:

• It cannot be removed from the shared block list — this list is maintained collectively across all users.
• To still receive calls or messages from that number, add it to your contacts: LLort automatically whitelists all your contacts.
• If you believe the community database made a mistake, please report it via email or Discord (links available in the app settings).

If you blocked the number yourself by mistake:

• Go to Menu → Blocked Numbers and unblock it directly from there.

Regarding blocked keywords (community rules):

• Community keyword rules cannot be individually disabled.
• This only affects spam tagging — a matched keyword does not prevent SMS from being delivered. The message will still arrive, but the sender will be flagged as suspicious.
• To report a false positive, contact us via email or Discord (see app settings).

LLort filters SMS that match known spam patterns or numbers reported by the community. However, a spam SMS might still reach you because:

• The sender's number is not yet in the community database — spam databases are never 100% complete.
• The message does not match any known keyword pattern.
• Android SMS filtering permissions are not fully granted — check Settings → Apps → LLort → Permissions.

If you receive a spam SMS, please report the number directly from the message thread. Every report strengthens the database for the whole community.

LLort blocks unwanted calls and SMS through two mechanisms, which are counted separately.

Automatic kills are blocks triggered silently by LLort without any action on your part — the number matched a community-reported pattern or a known spam database entry, and the call or message was stopped before it reached you.

Manual kills are blocks you triggered yourself — by pressing the Countermeasure button, by blocking a number from a call or message thread, or by adding a number to your personal block list.

The Global counters show the combined totals across the entire LLort community. The Local counters show only your personal activity on this device.

When you report a number as spam, LLort sends the following to its servers: the phone number, the type of report (call or SMS), and an anonymous session token.

Your personal identity — name, phone number, email address, or any billing information — is never attached to a report. The token is a one-way cryptographic signature that proves the report came from a legitimate LLort account without identifying you.

Reports are aggregated across users. A number only becomes community-flagged once it reaches a certain threshold of independent reports, which limits the impact of false or malicious reports.

For French users — 33700 reporting: LLort also offers an optional integration with 33700, the national SMS spam reporting service operated by AF2M. This is a separate, external service. When enabled (Settings → Messages → Automatically report spam messages to 33700), LLort will ask for your explicit consent before forwarding any report. Data sent to 33700 includes your phone number, the sender's number, the message content, and the date and time of receipt. This data is processed by AF2M under its own privacy policy, independently of LLort. You can disable this option at any time from the settings.

LLort is a community application to protect against scams, fraud, and intrusive advertisements by sharing useful information between users. Connecting and sharing data requires infrastructure such as servers, people, and time to maintain services. As we do not want to fall into business models that rely on selling personal data or adding advertisements, we are counting on your satisfaction to show us your support by subscribing!

Although we appreciate your support, we do not want to store sensitive information about you on our servers. Registering multiple devices means setting a specific account for each user with several pieces of information — which means more resources and more threats. We hope you will appreciate that we keep the subscription amount as low as possible to make it affordable even if you have multiple devices.

We sincerely thank you for your willingness to support LLort. The information requested depends on how you subscribe.

• Subscription via the Google Play Store
Payment and billing are handled entirely by Google. Your payment and billing data are collected and processed by Google under its own privacy policy. LLort neither collects nor has access to this data: we only receive a confirmation token from Google to activate your subscription. LLort does not ask you for any personal information.

• Subscription via direct download (Revolut payment)
French regulations require us to issue an invoice for every subscription, which means we must collect your billing information (name, address, etc.). We cannot exempt ourselves from this legal obligation. Your data is never collected or used for any purpose other than complying with French billing regulations and maintaining internal accounting records; it is processed in full compliance with the General Data Protection Regulation (GDPR) applicable in the European Union. Payment itself is handled by our provider Revolut: we never have access to your banking details.

Your PIN is your personal identity key inside LLort. It is used to authenticate you with the LLort servers and to protect access to your account — not to lock the app itself.

You set it once during the first launch. After that, LLort uses it silently in the background to sign your requests and verify that they come from you. Nobody else can report numbers or access your subscription on your behalf without it.

Your PIN is never stored in plain text, neither on your device nor on our servers. Keep it somewhere safe — if you lose it, see the dedicated FAQ entry on PIN recovery.

Your PIN is the key to your LLort account. For your privacy, it is stored encrypted and LLort does not keep a copy that could be used to identify you.

If you lose your PIN, don't panic — a reset flow is available. The next time you open the app, you will be guided through the steps to reset it.

To complete the reset, you will need the email address linked to your phone number at the time of your first registration. LLort will then send you a two-factor authentication code to verify your identity and allow you to set a new PIN.

Your subscription remains linked to your device throughout the process.

Your account is linked to your phone number and your PIN. When you reinstall or switch phones, you will be prompted to re-authenticate with your PIN. LLort will verify your identity using the phone number associated with your account and your subscription will be recognised automatically.

Your call log and message history are stored locally on your device. They are not backed up to LLort's servers, so a reinstall or a phone change will result in a fresh local database.

Your contacts are stored locally on your device and managed by Android. They will reappear automatically as soon as LLort has permission to read them — no action required on your part.

Your personal block list is also stored locally. We recommend noting down any numbers you have blocked manually before switching devices.

You can delete your account directly from the app Settings:

• Open LLort and go to Settings (gear icon, top right).
• Tap Delete my profile.
• Confirm the deletion.

Data stored on our servers:

The only personal data stored in plain text is your email address. Your account identifier (UID) is a cryptographic hash derived from your phone number and PIN — your phone number and PIN are never stored as-is and cannot be recovered from it.

What is deleted: your email address, your UID, and your subscription status and history.

What is retained: reports you contributed to the community database — fully anonymised, they cannot be linked to your identity and continue to protect other users.

Local data: your call log, messages and contacts are stored locally on your Android device and managed by the system. Deleting your LLort account does not erase them. To remove this data, use Settings → Apps → LLort → Clear data.

If you encounter a problem or wish to exercise other data rights (access, rectification, portability), contact us at contact@llort.tel.

FakeCall lets you trigger a simulated incoming call at any moment — useful when you need a convincing excuse to exit a situation (a meeting, an awkward conversation, or anything else).

You can schedule it to fire after a short delay, choose the name and number that appears on screen, and even have a voice speak on the other end so the call feels real to anyone nearby.

To set one up, go to the FakeCall option in the app menu. You can configure the delay, the caller identity, and the voice message before triggering it.

LLort works without an internet connection — provided it has completed its first synchronisation with the server during the initial setup.

Important: an internet connection is mandatory on first installation. LLort must authenticate you before it can operate. If it cannot verify your account, it will refuse to function.

Once that first sync is done, LLort can run offline:

• Calls and SMS work normally, just like any phone app.
• Spam detection continues to work based on the community data downloaded during the last synchronisation.

However, without a connection, LLort cannot:

• Update its community block lists — the data will become increasingly outdated over time.
• Report a number as spam or safe.
• Activate the Countermeasure sequence.

We recommend staying connected periodically so that LLort's protection remains up to date.

Visual voicemail is a feature that depends entirely on your mobile carrier — not on the phone app itself.

To support it, a carrier must expose a specific API or proprietary protocol that allows the dialer to fetch, play, and manage voicemail messages directly within the app. This API varies from one carrier to another, is often closed, and is generally reserved for apps pre-installed by the carrier.

LLort does not have access to these APIs. Even Google, with its official Phone app, only supports visual voicemail on a limited number of partner carriers.

In the meantime, you can reach your voicemail in two ways:

• From Settings → Create voicemail shortcut — this creates a one-tap call shortcut to your voicemail.
• From the LLort dialpad: press and hold the 1 key — Android will automatically dial your voicemail number.

The advanced protections, customisation options, and system interactions that make LLort what it is on Android simply cannot be replicated on iOS.

Apple's platform imposes strict restrictions on what third-party apps can do at the system level: replacing the default phone app, intercepting calls before they ring, filtering SMS at a low level, or accessing notification data are either forbidden or heavily limited on iOS.

Building a watered-down version that could not deliver the same level of protection would go against what LLort stands for. We prefer to do one thing well rather than two things poorly.
